This paper presents the results of an experimental program aimed at using expanded polystyrene (EPS) wastes in developing lightweight mortar and masonry solid brick units of adequate mechanical and thermal characteristics for use in building and construction applications. Five dosages of EPS were used to partially substitute the sand in the mix, namely; 0, 10, 15, 20 and 26 kg/m³. The results showed that the density, compressive strength, tensile strength, static modulus of elasticity, and coefficient of thermal conductivity decrease with the increase of the EPS dosage in the mix. The results showed also that the proposed EPS solid bricks possess adequate strength for non-loadbearing applications have superior thermal properties.

本文介绍了一项实验计划的结果，该计划旨在使用膨胀的聚苯乙烯（EPS）废物开发具有足够机械和热特性的轻质砂浆和砖石实心砖单元，以用于建筑和建筑应用。使用五剂EPS来部分替代混合物中的沙子，即：0、10、15、20和26 kg / m ³。结果表明，随着混合物中EPS用量的增加，其密度，抗压强度，拉伸强度，静态弹性模量和热导率均降低。结果还表明，所提出的EPS实心砖具有足够的强度，适用于非承重应用，具有优异的热性能。
