The increasing challenges in natural resource consumption and cement production have intensified interest in recycling and sustainable construction materials. In this study, an environmentally friendly lightweight geopolymer concrete (LWGPC) was developed by integrating two recycled components: fly ash (FA) as the primary binder and a novel lightweight coarse plastic aggregate (LCPA), produced from locally recycled plastic was...

This study uses a few materials with various ratios, such as sugarcane bagasse ash (SBA) and macro synthetic fiber (MSF), to enhance the rigid pavement slab (RPS) load-carrying capacity (LCC). In the study presented herein, the investigation was developed in two phases. Firstly, we selected materials and evaluated their physical, mechanical, and chemical characteristics. Nine different concrete mixes were designed as part of t...
