Effect of Ceramic Waste Aggregate in Concrete to Reduce Environmental Pollution

Abstract

The utilization of ceramic waste is one solution to reduce environmental pollution due to development waste. The aim of this study was to utilize ceramic waste as a concrete aggregate material. The test consisted of the mechanical properties test of ceramic waste aggregates and the compressive strength test of ceramic concrete. The variation of normal aggregate partial replacement with the aggregate of CWA is 0%, 25%, 50%, 75%, and 100%. The total number of specimens is 50 cylinders. From the results of material testing and ceramic concrete tests showed that ceramic waste aggregate can be used as concrete aggregates, especially for elements that accept compressive forces, shear forces, and in-plane forces. The X-ray test shows that CWA aggregate is not pozzolanic, so it can be used as a concrete aggregate to reduce environmental pollution. The percentage porosity of ceramic concrete is smaller than the porosity of normal concrete. The effect of partial replacement of normal aggregate with the CWA aggregate in concrete optimum at a value of 55% CWA aggregate.
