Application of Environment-Friendly Building Materials in the New Countryside

Due to the high cost of environment-friendly materials and limited funds for the new countryside construction,it is the principal contradiction in the application of environment-friendly materials to satisfy the demands of both environment protection and cost reduction.The authors proposed that the influence ranking of these materials on environment should be clarified first to settle this contradiction,that is,to choose energy-conserving and environment-friendly materials within the limit of expenditure.By comparing the energy consumption,shock resistance,economic efficiency and social acceptability of wall materials,the influence ranking was given as below:hollow concrete block < lime-sand brick < baked chamotte brick;by analyzing the advantages and disadvantages of floor and roof concrete materials,as well as attentions for reducing negative impacts,the order of their influence was given as below:precast concrete trough plate < precast hollow strength concrete plate < cast-in-place concrete plate < cast-in-place brick-concrete plate;suitable materials for door and window frameworks were concluded,the influence order of wall and floor decoration materials on environment was given as:bare walls without plastering < walls of stable soil plastering < walls of cement-water plastering < walls of lime plastering;concrete for the overall decoration < parquet floor < tile floor < terrazzo floor;and 7 heat retardation materials were suggested for the construction of new countryside.

The Application of Solid Waste in Thermal Insulation Materials: A Review

As socioeconomic development continues,the issue of building energy consumption has attracted significant attention,and improving the thermal insulation performance of buildings has become a crucial strategic measure.Simultaneously,the application of solid waste in insulation materials has also become a hot topic.This paper reviews the sources and classifications of solid waste,focusing on research progress in its application as insulation materials in the domains of daily life,agriculture,and industry.The research shows that incorporating household solid waste materials,such as waste glass,paper,and clothing scraps into cementitious thermal insulation can significantly reduce the thermal conductivity of the materials,leading to excellent thermal insulation properties.Insulation materials prepared from agricultural solid waste,such as barley straw,corn stalk,chicken feather,and date palm fibers,possess characteristics of lightweight and strong thermal insulation.Industrial solid waste,including waste tires,iron tailings,and coal bottom ash,can also be utilized in the preparation of insulation materials.These innovative applications not only have positive environmental significance by reducing waste emissions and resource consumption,but also provide efficient and sustainable insulation solutions for the construction industry.However,to further optimize the mix design and enhance the durability of insulation materials,continuous research is required to investigate the mechanisms through which solid waste impacts the performance of insulation materials.

The study suggested a checklist to help assess the condition of buildings in Palestine and the extent to which they respond to the principles of sustainable green buildings, thus, contributing to help new and existing buildings to adopt a sustainable green building approach, in order to achieve the goals of sustainable green construction in terms of saving energy and resources and reducing waste, therefore, participating in preserving the environment and improving the quality of life.

SUSTAINABLE DESIGN AND ENERGY CONSUMPTION ANALYSIS FOR STRUCTURAL COMPONENTS

The engineering community has been striving to design more sustainable buildings in an attempt to reduce both environmental impact and energy use during all phases of design,construction and operation.Design professionals currently have very limited guidance or tools to incorporate life-cycle and sustainability concepts into their designs.After reviewing the capabilities and limitations of four current life cycle analysis(LCA)computer programs,this research has selected the Athena Impact Estimator v4.0 to perform parametric studies of structural members made up of different construction materials.The energy consumption values are calculated and compared for columns,beams,concrete suspended slabs,precast double-tee sections and various other floor types.While Athena did offer some insights based on its LCA results,this research has concluded that existing LCA and sustainability analysis programs have too few options to meet the current needs of design professionals.A more accurate,sophisticated whole-building LCA tool needs to be developed to assess sustainable properties of design alternatives and to produce the most sustainable structural systems.

磷石膏的综合利用及其在建筑材料领域的应用研究进展

磷石膏是湿法制备磷肥工艺过程中的副产物,主要物相是CaSO_(4)·2H_(2)O。我国磷石膏产量居世界第一,综合利用率却不到50%,堆存量已达8亿吨,对生态环境造成了严重破坏,因此,探索磷石膏的有效利用途径已迫在眉睫。本文对磷石膏综合利用主要领域的研究现状进行了分析,其中磷石膏在化工领域的利用率仅有5%,在农业领域的利用率也只有2%,而建筑材料领域是目前磷石膏的主要应用领域。目前将磷石膏应用于水泥缓凝剂、石膏砌块和水泥砂浆已经实现了工业化;将磷石膏应用于胶凝材料和路基材料,由于浸出毒性的问题,并未大规模应用;将磷石膏用作填充剂则因为材料强度较低,仅仅停留于实验室探索阶段。最后展望了未来无害化利用磷石膏技术研究的发展趋势,以期为解决磷石膏的堆存问题提供参考。

Synthesis and Characterization of Local Bio-Sourced Geopolymer Binder: Application to Compressed Earth Blocs

The construction industry continues to rely on conventional materials like cement,which often can come with a high cost and significant environmental impact,particularly in terms of greenhouse gas emissions.To tackle the challenges of sustainable development,there is growing interest in using local available materials with low environmental impact.This study primarily focuses on synthesizing and characterizing a geopolymer binder made from local materials found in Benin to stabilize CEB(compressed earth brick).The synthesis involves combining amorphous aluminosilicate powder with a highly concentrated alkaline solution.Local calcined kaolinite clay(metakaolin)and corn cob ash obtained after calcination at 600°C were used with a 12 M sodium hydroxide(NaOH)solution.Different mixtures of geopolymer were formulated substituting metakaolin by corn cob ash at rates of 0%,5%,10%,and 15%of the dry weight of the mixture.Thereafter physical and mechanical characterization tests were conducted on each formulation.Results showed that geopolymer binders containing 85%metakaolin and 15%corn cob ash exhibited the best physical and mechanical performance(e.g.12.08 MPa for compression strength).Subsequently,this geopolymer formulation was used to stabilize CEB.Characterization revealed that CEBs stabilized with 10%geopolymer exhibit good mechanical properties(6.93 MPa),comparable to those of CEBs stabilized with 10%cement(7.40 MPa),justifying their use as load-bearing walls in construction.
