The study of the effects of using ceramic waste as eco-friendly alternative for fine aggregates in plastering CHB wall

Abstract

The rapidly growing population has increased construction, repair, and remodeling activity, which has resulted in considerable construction material waste. One problem contributor that might lead to land pollution is the disposal of broken ceramics. On the other hand, natural resources used in building, such as fine aggregates, are depleting to meet future demand. Related studies did not provide the actual implementation of their research findings. As such, the focus of the researchers is on the partial substitution of ceramic waste as fine aggregate in the plastering of CHB walls. The replacement comprises 0%, 20%, and 30% of the mixture. A series of tests were conducted, such as the slump cone test (per ASTM C143), compressive strength test, and split tensile strength test. As the study progresses, the 20% combination produces inconsequential results for compressive and split tensile strength tests. Internal (8mm thickness) and external (16mm thickness) plasters were made in single coats only on the 12.356 square meter wall area using the prevailing 20% mixture. The results show that a 20% pulverized ceramic waste substitute for fine aggregates in plastering CHB walls is feasible.
