Abstract

Concrete is a material that has a high compressive strength but has a low tensile strength and has a high density. To solve its weakness, reinforcement steel bars are used to resist the tensile strength and lightweight coarse aggregates are used to reduce the concrete density. The purpose of the research is to determine the impact of substituting normal coarse aggregates with clay roof tile fractions on concrete density, concrete cylinder compressive strength, and reinforced concrete beam flexural strength. The samples are concrete cylinders and reinforced concrete beams, with 3 samples for each substitution variation. The variations are 0%, 20%, 40%, 60%, 80%, and 100%. All samples are tested after 28 days. The tests are obtained maximum pressure force data. The data are processed to obtain the research results. The calculation found that samples with 100% lightweight coarse aggregate proportion have the lowest density of 1868.58 kg/m3. Also, the result of compressive strength is between 29.071 MPa and 20.054 MPa. And the result of flexural strength is between 14.650 MPa and 11.391 MPa.
