Sifat Fisis Tanah Lempung Ekspansif yang Disubstitusi dengan Serbuk Limbah Keramik

Expansive soils have high compressibility, swelling, and shrinkage properties. So we need an effective method to improve soil conditions when the structure is built on it. This paper presents results of research effect substitution ceramic waste physical properties expansive soil. Soil improvement using construction will contribute reducing amount conserving natural resources. The stages included testing both materials, then mixed which Atterberg limit test, compaction SEM test. addition powder can function as a material that chemically change There was decrease in optimum water content (wopt) increase maximum dry density (gd max) value along with percentage up 1.410 gr/cm3. chemical (SiO2 Al2O3) affects parameters decreases plasticity index, where SiO2 Al2O3 1 higher than 2 giving lower IP (Index Plasticity) values moisture content, respectively by 16.26 28%, 14.4 gr/cm3.
