Analysis of Material Feasibility Testing of Ceramic Waste Fractions as a Substitute for Coarse Aggregates in Concrete

Analisis Pengujian Kelayakan Material Pecahan Limbah Keramik sebagai Pengganti Agregat Kasar pada Beton

Abstract

The ceramic industry generates considerable waste, including leftover raw materials, defective products, and ceramic fragments that fail to meet quality standards. This study investigates the feasibility of utilizing ceramic waste as a coarse aggregate substitute in concrete, focusing on its physical characteristics. Three fragment sizes—1 cm, 1.5 cm, and 2 cm—were tested using the Impact Test Value (ITV), Los Angeles Abrasion Test, specific gravity tests (bulk, SSD, and apparent), water absorption, and bulk density. All sizes met the eligibility requirements for coarse aggregate under SNI and ASTM standards. The average ITV was 3.17%, and the Los Angeles abrasion value was 29%. Specific gravity and water absorption were comparable to conventional aggregates. These results indicate that ceramic waste has strong potential as an environmentally friendly alternative to natural coarse aggregate in concrete construction, offering both sustainability benefits and comparable performance to traditional materials.
