Japanese,This paper proposes a cost estimation sheet supporting decision making for city planning. The urban form is represented by 30 by 30 cells on the sheet and the cost is estimated regarding population distribution, population projection, maintenance cost of road network, water supply and sewerage network, and investment for new development site. The sheet first requests its user to input current population distribution and several cost parameters. Then the sheet designates the downtown cells. A distance from closest downtown cell is calculated for each cell, which is used for cost estimation. User will be asked to finalize the spatial plan where cells are given the following labels; downtown, to be developed as new sub centers, to be disengaged. The maintenance cost is calculated by number of cells, distance from closest downtown, and population within the cell. Finally, the sheet gives how long does it take until the saving of maintenance cost by disengagement will balance the development cost of new sub centers.

Japanese, The aim of this study is to qualitatively evaluate the cracking control effects of expansion concrete used in reinforced concrete building. The result of experiments in laboratory shows that autogenous shrinkage and drying shrinkage are suppressed by using expansive additive. The tensile stress-strength ratio is lower in expansion concrete than normal concrete under fully restrained condition. Compression stress could be effectively generated in early age in the walls and slabs in buildings by the use of expansive additive, and tensile stress due to drying shrinkage at later age eventually decreased. Additionally, visual observation at long-term ages shows that the cracking area of expansion concrete was approximately 35% of normal concrete, which confirms that the use of expansive additive reduces concrete cracking in reinforced concrete buildings. - Mechanical Property of Polymer Cement Mortar at High Temperature

Japanese, Objective. This study proposes a comprehensive method for calculating transporting distance on ecoMA. Moreover, as an example of the method’s application, the study conducted a simulation of material flow that meets the fresh concrete demand in four prefectures of Kanto region and calculated CO2 emissions from the process of production and transportation.
Results and Discussion. The share of CO2 emissions from transportation was 5.7% for road distance, which was 1.2% higher than when linear distance was used. It was understood that total amount of CO2 emissions from transportation is 1.3 times that of emissions when linear distance was used. Looking at the transportation of crushed stone, sand, cement (cement service station – fresh concrete factory) and cement (cement factory – cement services station), road distance was between 1.30 and 1.43 times greater than linear distance. For transportation of products other than fresh concrete, it was understood CO2 emissions for road transportation are much higher than those for linear transportation. Furthermore, for cement (cement factory – cement service station), the ratios of CO2 emissions for linear distance and road distance were large compared to crushed stone and sand, which are often transported over long distances from the suburbs to urban centers, and therefore it was understood that transportation distance caused by use of road distance depending on material types as well as geographic characteristics.
Conclusions. By providing an example of ecoMA with a calculation module that can take road distance into account, this study demonstrated that it is possible to calculate CO2 emissions accurately with consideration for road distance. As a result, it has become possible to quantitatively calculate how much larger CO2 emissions are for road distance when compared to linear distance. - COMPLETELY RECYCLABLE CONCRETE OF AGGREGATE-RECOVERY TYPE BY USING MICROWAVE HEATING

Japanese, A comprehensive model for wood flows in Japan based on the statistics points out inefficiency that a lot of domestic thinned woods are disposed in spite of the consumption of non-cyclic forest resources from foreign countries for domestic use. Moreover, the model explains that various recycled products made of woodchip would cause decay of flexibility receiving secondary woodchip into the flow. Therefore, new methodologies are required to assess building materials supporting flexibilities of material flows for a dynamic sustainable society as well as existing methods of environmental assessment such as CO2, wastes, and resource consumptions. In existing researches the concept of "a sustainable society" has usually represented "a static society", but a society dreaming of "much more sustainable society" is not necessarily static forever even if material flows look sustainable. In this paper, Aptitude items for a dynamic sustainable society are designed and their effectiveness has been confirmed for assessing wood materials to satisfy these requirements. - QUANTITATIVE EVALUATION OF VISUAL INFORMATION OF EXPOSED CONCRETES BY 2DIMENSIONAL FOURIER TRANSFORMATION

In the domestic construction industry, technological development for CO2 fixation is progressing. In the construction waste processing sectors, It is known that “recycled concrete roadbed” has CO2 fixation performance because it was made of concrete demolition waste. It has a larger surface area than conventional concrete structures, enabling them to fix CO2 from the atmosphere simply by being placed in stockyards. To address this, we has launched a working group aimed at equipping recycled concreate roadbed manufacturers with the essential knowledge and expertise needed to understand the amount of CO2 fixed during the recycled concrete roadbed manufacturing process. As a result, conducted a nationwide survey on CO2 fixation in concrete waste achieves the results which are comparable to those from a similar study conducted 16 years ago., Japan Society of Material Cycles and Waste Management, Japanese - Amount of water added at the time of residual concrete removal by installing a flow meter

“Fresh ready-mixed concrete waste” at construction sites is defined as fresh concrete that is leftover after castingbecause the amount of ready-mixed concrete ordered by the construction site was larger than the required amount.When the ordered quantity of ready-mixed concrete falls short of the required quantity, it has a significant impact on the construction schedule. This is a problem which is difficult to completely eliminate whether the quantity is small or large. It is therefore an issue to be solved from the viewpoint of sustainability in concrete distribution, especially from the viewpoint of waste recycling. Possible reuse methods are beingstudied from various angles by various companies, and one of the most common methods is to use fresh ready-mixed concrete waste to make concrete blocks. In this manuscript, based on the fundamental research presented so far, this paper describes the factors necessary for the advanced utilization of fresh ready-mixed concrete waste., Japan Society of Material Cycles and Waste Management, Japanese - 残コンを再利用したブロック製品の形状に関する全国調査

We have been developing IoT sensors for the evaluation of the comfort levels of real estate building properties. In this paper, we additionally evaluated thermal insulation performance and sound performance. In addition, we added a PM2.5 sensor. We are now conducting a large-scale experiments using $60+$ properties to assess the system' usability and reliability., The Japanese Society for Artificial Intelligence, Japanese - Health monitoring of tile structures via non-contact laser excitation/measurement technique
SUZUKI Kengo; SASAKI Motoaki; SAITO Ryosuke; KITAGAKI Ryoma; KAJIWARA Itsuro, The Proceedings of Mechanical Engineering Congress, Japan, 2019, 0, J40110P, 2019In this research, we propose a method to evaluate the adhesion of exterior tiles based on non-contact laser excitation/measurement technology using laser-induced plasma. In this method, laser ablation is used for excitation, and a laser Doppler vibrometer is used for measurement. A test specimen including tiles with insufficient adhesion is manufactured and evaluated. As a result of the laser excitation experiments, we found that the power spectrum increased in a specific frequency band at the floating part compared with the sound part. Furthermore, RT method was applied to the measurement data, resulting in a quantitative extraction of characteristic change due to the insufficient adhesion of the tiles.

日本国内の人口10~30万人の中堅都市は,ここ10年来毎年平均1%~3%程度の人口減少を続けている都市も少なくない.これらの都市は,近年,サービス施設の休廃止・統廃合といった公共サービスの提供エリアを選択的にすることで行政を効率化し,さらに,都市域の縮小化「縮退戦略」を進めることも視野にいれており,なるべく住民の満足度を維持しながら,都市運営の効率をあげる方法を検討している.そこで,本研究では,人口減少している都市の一つである群馬県とくに桐生市を対象に,ごみ処理焼却施設の休廃止をするかわりに,低コストで管理できるコンポスト施設を設置することによって得られる費用便益効果およびCO2排出量削減効果の比較を試みた.ごみ焼却サービスの提供範囲を狭めながらも,低コスト・低環境負荷の代替施設を設置することによって,都市全体のコストとCO2排出量を下げながらも,住民の満足度を下げず,都市としての運営効率をあげる可能性が確認された., The Institute of Life Cycle Assessment, Japan, Japanese - Scenario evaluation for reducing the environmental load of concrete-related industry

In order to develop new eco-friendly building materials, authors tried making non-baked tile by densification of powders through carbonation and hydration after pressure forming. The studies on properties of casting calcium carbonate by same process have been already done by Arinaga. In this study, to make improvement of the casting calcium carbonate and apply the process to recycle by-product powder derived from used concrete, authors produced some kind of tile material experimentally and investigated the properties of them. In the result, authors presented the possible way to produce tile material by simple and energy saving process mainly using by-product powder which effective way of recycling is strongly hoped for., Japan Society for Finishings Technology - 1617 Development of Resource Flow Simulation System of concrete related materials : Vol. 7 Comparison of environmental impacts between Tokyo and Hokkaido

インドネシアのメダン市は、北スマトラ州にあるインドネシア第三の都市である。本稿は、2007年1月8日〜22日に東京大学都市再生COEの活動の一環として、メダン市の建築ストックの性能劣化実態調査および現地生コンクリート製造企業に対して実施したヒアリング調査に基づき、一般的な建築ストック寿命から試算した場合の建設系資材(とくに、セメントとコンクリート系廃棄物)の需給バランスについてシミュレーションによる予測試算を実施し、これを報告するものである。現地建築ストック劣化調査については、(1)都心部のRCレンガ壁式住宅の新築について、材料・施工方法の観点から施工品質調査を実施し(2)都心部街区の一区画を選定し、建物群の劣化調査を実施した。その結果、発展途上国都心部の建築ストックによくみられる脆弱な構造のみならず、それ以前に、現地の気象の影響によって、通常はそれほど管理するのが高度ではない施工品質が要因となり、経年劣化・脆弱化していると考えられる箇所が頻繁に見られることが明らかになった。次に、現地の代表的な生コンクリート製造企業に対して、現地生コンの消費量および材料調達の方法、価格などについてヒアリングし、メダン市の人口増加状況から、今後のセメントの需要、建築ストック解体ラッシュのピーク時期とコンクリート系廃棄物について都市計画的観点からシミュレーションを実施し、考察を行った。今後数年間、現在のペースで成長を続けることによって、メダン市だけで、ピーク期には現在の東京都の約8.0倍程度のコンクリート系廃棄物が年間排出される勢いになると予測された。, 日本建築仕上学会, Japanese - Calculation of specific environmental load consumption in concrete related industry considering the local communities

Reduction of CO2 emission is one of the most important tasks for the construction industries in many countries, since they cover high ratio in the total emission. On the other hand, reduction of waste emission is another important task for the construction industries in highly populated countries, such as Japan, because of the depletion of landfill sites. Among the whole construction industries, concrete is the most widely and long-term used material. Some of the researchers has qualitatively pointed out that the amount of demolished concrete, especially those used in 1970s, is expected to cause a severe damage on the depletion of landfill sites. To solve the problem, there have been many technical and social proposals. In this paper, to find an optimal material balance and social circumstances for the proposal, we have firstly developed a resource-flow simulation system using the concept of Multi-Agent-System. Secondly, using the system, comparative case studies have been made to examine two typical and prospective proposals; high quality recycled aggregate, and enlargement of building lifetime. The studies have shown that even in the idealistic situation where recycled aggregate is aggressively used despite of its high price, the predicted amount of demolished concrete is overwhelming. The studies have also shown that in the idealistic situation where building lifetime is unrealistically long, the amount of demolished concrete can be reduce on some level., The Institute of Life Cycle Assessment, Japan, Japanese - 1631 Evaluation on "Eco-material" of Wooden Materials

Eco-labeling systems to products,which have an advantage of environmentall aspects,are very effective to spread and make them known for uuse.However,many eco-labels have not been established on numerical standards,and so it is very difficult to select an appropriate product from all kinds of eco-materials.We have investigated faxtories of wooden building materials with eco-labels in Japan,and evaluated LCCO2,LCW of each material.As a result,LCCO2 and LCW of materials with the same eco-label are not necessarily similar with each other,therefore,the numerical evaluation methods for eco-materials are required in the near future., Japan Society for Finishings Technology - Prediction of concrete-materials related waste :resource-flow simulation using multi-agent-system

2019 - 2019,In this research, we propose a method to evaluate the adhesion of exterior tiles based on non-contact laser excitation/measurement technology using laser-induced plasma. In this method, laser ablation is used for excitation, and a laser Doppler vibrometer is used for measurement. A test specimen including tiles with insufficient adhesion is manufactured and evaluated. As a result of the laser excitation experiments, we found that the power spectrum increased in a specific frequency band at the floating part compared with the sound part. Furthermore, RT method was applied to the measurement data, resulting in a quantitative extraction of characteristic change due to the insufficient adhesion of the tiles.

2010 - 2010, 日本国内の人口10~30万人の中堅都市は,ここ10年来毎年平均1%~3%程度の人口減少を続けている都市も少なくない.これらの都市は,近年,サービス施設の休廃止・統廃合といった公共サービスの提供エリアを選択的にすることで行政を効率化し,さらに,都市域の縮小化「縮退戦略」を進めることも視野にいれており,なるべく住民の満足度を維持しながら,都市運営の効率をあげる方法を検討している.そこで,本研究では,人口減少している都市の一つである群馬県とくに桐生市を対象に,ごみ処理焼却施設の休廃止をするかわりに,低コストで管理できるコンポスト施設を設置することによって得られる費用便益効果およびCO2排出量削減効果の比較を試みた.ごみ焼却サービスの提供範囲を狭めながらも,低コスト・低環境負荷の代替施設を設置することによって,都市全体のコストとCO2排出量を下げながらも,住民の満足度を下げず,都市としての運営効率をあげる可能性が確認された. - Componential analysis of inorganic building material:Fundamental study for establishing total recycling system of building material

2010 - 2010, 現在無機建材のほとんどは供用期間を経たのち粉砕して最終処分されている。しかし、有限の資源を有効活用するためには全量リサイクルできるシステムを確立するのが望ましい。そのリサイクルの手法の一つとして、無機建材廃棄物の成分を適切に混合し成形、焼成などを行い再利用することが挙げられる。その適切な混合を定めるために、蛍光X線分析装置を利用し無機建材に含まれる成分を分析することを目的とする。 - Simulation System for Calculating Regional CO2 emission of Building Materials Employing Actual Road Distance Calculator

2009 - 2009, In order to develop new eco-friendly building materials, authors tried making non-baked tile by densification of powders through carbonation and hydration after pressure forming. The studies on properties of casting calcium carbonate by same process have been already done by Arinaga. In this study, to make improvement of the casting calcium carbonate and apply the process to recycle by-product powder derived from used concrete, authors produced some kind of tile material experimentally and investigated the properties of them. In the result, authors presented the possible way to produce tile material by simple and energy saving process mainly using by-product powder which effective way of recycling is strongly hoped for. - Development of Simulation System for Calculating Regional CO2 emission of Building Materials Employing Actual Road Network

本研究は、研究代表者が近年開発した、反応界面における局所的なpHおよびCaイオン濃度変化を蛍光プローブを用いて可視化する技術を、多様な材料に適用できるように高精度化・汎用化することを目的としている。2022年度においては、以下について研究を進め、成果を得ている。
[1]ゲル内二重拡散法によって合成される炭酸カルシウムについて、形成環境のpHの可視化に成功した。ゲル全体のpH変化を可視化した結果、多形によって形成環境のpHの変化の傾向が異なることが明らかになった。さらにレーザー共焦点顕微鏡を用いた詳細な観察により、カルサイト成長時の結晶近傍のpHに局所的な不均一が生じることを初めて確認した。しかし、アラゴナイト形成場の近傍にはこのような傾向は観察されず、このような形成場の局所的な環境の違いも多形形成に影響を与えている可能性が示唆された。
[2]従来までに観察可能であることが示されている炭酸カルシウム以外の材料についての適用を進めた。特に、リン酸カルシウム系の材料について、溶解時のpH変化およびCaイオン濃度分布の変化を可視化したところ、アパタイトやリン酸八カルシウムなど、物質によって異なる傾向を示すことが観察された。さらに、同じ物質であっても、Naが含有しているものは、含有していないものとは大きく異なるpH変化の傾向を示すことが明らかになった。このことは、生体材料としてリン酸カルシウムを用いたり、生体内でのリン酸カルシウムの形成過程を理解する際の指針となる。

In construction, combination of organic adhesives and inorganic substrates are used in a variety of situations, from new construction to renovation. They are expected to have high adhesive strength and can be easily and quickly installed. But the mechanisms of adhesion and deterioration have not been sufficiently discussed. In this study, to evaluate the interfaces of adhesives and inorganic substrates, we applied the methods used in the field of polymer physics to measure the type and density of chemical bonds and the pore structure to the interfaces of building materials.
Samples assuming the interface between inorganic substrates and organic adhesives: composite consisting of powdery inorganic materials and organic adhesives were made and sized to the free films. After accelerated weathering test, we observed reactions between inorganic substrates and organic adhesives through results by chemical analysis discuss the mechanism of deterioration in detail.

A maximum strength of about 100MPa is achieved by using modified powders of by-products and wastes, amorphous powders that are naturally unused resources, alkali stimulants, shrinkage reducing agents, etc. without using Portland cement. At the same time, we researched and developed concrete that is less likely to shrink and crack. In addition, we will verify the durability and recyclability of the concrete, evaluate the carbon dioxide emissions at the concrete manufacturing stage, use stage, and disposal stage, and have high salt permeation resistance and high suppression of the alkali-silica reaction of the aggregate. We have developed concrete that can be recycled as a raw material for cement after disposal, and has a negative carbon dioxide emission over the entire life cycle.

The bond splitting strength of low quality recycled aggregate concrete beams using vinylon fiber were studied. Compared with the case of normal aggregate concrete, the above-recycled concrete beams with vinylon fiber showed equivalent flexural cracking pattern under service loading, values of bond splitting strength at lap splices. This suggests that low quality recycled aggregate concrete could be used as a structural concrete material.

(1) Development of deterioration testing equipment which can control the deteriorating factors separately including UV.(2) Gas permeability and diffusion coefficient of coatings are measurable with Thermal desorption system (3) Most building coatings are thought to be glass formation as rubber formation polymer where gas permeates and diffuses not depending on Fick’s law and Henry’s law. (4) Gas permeability and diffusion in building coatings transit behavior depending on temperature and humidity condition.(5) Interaction between gas species in diffusion process of building coatings is observed using TDS measurement.(6) Free volume theory should be introduced for understanding gas diffusion transition in building coatings under several temperature and humidity condition.
