Optimization Of Plastic Waste Integration In Cement Bricks, Yara Salah El-Din El-Metwally
Architectural Engineering
Implementing plastic waste in construction materials is a sustainable disposal method to overcome plastic pollution. The current study aims to optimize the integration of plastic waste in cement bricks regarding their thermomechanical properties in order to develop an eco‑friendly building material. Polyethylene terephthalate (PET) and high‑density polyethylene (HDPE) partially substituted cement with different ratios (0, 2.5, 5, 7.5, 10, 20%). The type that achieved better thermomechanical performance further replaced the other brick components; sand and coarse aggregates to determine the optimum replacement scenario and best design mix. Laboratory experiments have been carried out to measure the compressive strength, indirect tensile …

Over the last decades, plastic waste (PW) has increased exponentially and has become a serious threat to our planet, aquatic system and human health. Recycling or reusing PW in producing ecofriendly materials is an efficient solution to reduce plastic pollution and to minimize the depletion of raw materials as well. Previous studies have shown promising potentials of using PW in the construction sector, such as binder, aggregate, or substitute of cement and sand in concrete, brick or mortar. Laboratory results indicate that implementing plastic waste as aggregates in cement composites obtains higher thermal resistance and acoustical performance. However, a reduction …

Construction projects are associated with construction and demolition waste (CDW) generated at different stages. In Egypt’s case, the CDW problem has become a significant challenge, and the need to find sustainable solutions is overwhelming. Based on recent investigations in the literature, it was found that six main factors are affecting CDW reduction (CDWR) as follows: (1) waste-efficient materials procurement measures; (2) waste-efficient materials procurement models; (3) green materials procurement approach; (4) legislation; (5) culture & behaviour; and (6) awareness. In this study, a representative sample of Egyptian construction firms was screened to (1) investigate the applicability and effectiveness of CDWR …
