Abstract：
Construction and demolition waste, along with discarded PET plastic bottles, have evolved into a widespread global resource. However, their current disposal in landfills poses a significant environmental pollution challenge. This research is centered on evaluating the performance of cement mortar composed by larger PET particles in conjunction with sand, construction and demolition waste, and lightweight expanded polystyrene aggregates. The primary objective of this study is to formulate a blend suitable for non-structural elements that can be easily manufactured for social housing construction. This modified blend extends upon the original certified mixture employed at CEVE for brick production, which encompasses cement and 3 mm-long PET particles. The experimental analysis revealed that blend containing 8 mm-long PET particles, in combination with fine aggregates of construction and demolition waste, attained a required mechanical strength of 2 MPa, while preserving the bulk density and hydric properties of the initial PET bricks developed at CEVE in Argentina.
摘要：
建筑和拆除废物，连同废弃的PET塑料瓶，已经发展成为一种广泛的全球资源。然而,它们目前在堆填区的处置构成了重大的环境污染挑战。这项研究的重点是评估由较大的PET颗粒和沙子组成的水泥砂浆的性能，建筑和拆除废物，和轻质膨胀聚苯乙烯骨料。这项研究的主要目的是制定一种适用于非结构元素的混合物，可以很容易地制造用于社会住房建设。这种改性混合物在CEVE用于砖生产的原始认证混合物的基础上延伸，其中包括水泥和3毫米长的PET颗粒。实验分析表明，含有8毫米长的PET颗粒的混合物，结合建筑和拆除垃圾的细骨料，达到2MPa的所需机械强度，同时保留了阿根廷CEVE开发的初始PET砖的堆积密度和氢特性。
