The increasing demand for glass products has led to a rise in waste glass (WG), which is commonly disposed of in landfills, causing environmental degradation. Moreover, the direct adoption of a high volume of WG as aggregates in concrete can lead to

Abstract Lightweight aggregates are a material used in many industries. A huge amount of this material is used in construction and architecture. For the most part, lightweight construction aggregates are obtained from natural resources such as clay r

A sustainable concrete solution was developed by partially replacing aggregates and cement with lightweight plastic aggregates (LWPA) and bagasse ash, respectively. Three types of mixes were studied: (i) concrete with 10-30% cement replaced by bagass

The important way to obtain lightweight concrete with compressive strength, density, and thermal insulation properties that differ from normal concrete was by adding materials with cementitious properties to the concrete mix instead of cement or usin

Abstract Recent and past studies mainly focus on reducing the dead weight of structure; therefore, they considered lightweight aggregate concrete (LWAC) which reduces the dead weight but also affects the strength parameters. Therefore, the current st
