AAC WASTE,COCONUT COIR FIBRE,CEMENTMORTAR,,SAND REPLACEMENT.Abstract
AAC blocks are lightweight, thermally insulating materials used in modern construction, made from lime, cement, water, aluminum powder, calcined gypsum, and quartz sand. However, significant waste is generated during construction, processing, and transport, especially leftover pieces called bats, which are often discarded. Due to their low load-bearing capacity and environmental impact, proper reuse methods are needed.This study explores recycling waste AAC blocks as a partial replacement for sand in mortar (0%, 25%, 50%, 75%) and evaluates their compressive strength. Additionally, coconut (coir) fibers—a renewable and thermally resistant material—were added in varying percentages (0%, 0.5%, 1%, 1.5%) to enhance strength and performance of cement mortar.
