Mechanical Properties of Ceramic Waste as a n Alternative Material of Concrete Aggregate

Abstract

The increasing building construction in the field of civil engineering that requires supporting materials, starting in terms of human resources and material resources. Progress in the material field must consider energy-saving aspects. Therefore it is necessary to think about the use of useless materials such as ceramic waste. The purpose of this study is to see the potential of ceramic waste as an aggregate in terms of mechanical properties, with the hope of providing an alternative to concrete aggregates other than natural stone aggregates. Ceramic waste aggregate material testing is done by testing: chemical composition, absorption and water content, specific gravity, soundness, abrasion, granular form, gradation, and X-ray diffraction (X-RD). The test results show that the ceramic waste aggregate (CWA) can be used as a concrete aggregate. Ceramic waste aggregate (CWA) characteristics are sufficient to meet the standards as concrete aggregates according to the SII standard, BSI standard, and ASTM standards. While the X-ray diffraction test (X-RD) shows that no element damages concrete, there is no active silica that can react with alkaline cement and is not as a pozzolan.
