Abstract:
The modulus of elasticity of lateritic soil stabilized with cement types has been evaluated in this work. The aim of this study was to determine the modulus of elasticity of the lateritic soil before and after treated with cement types. The natural lateritic soil and lateritic soil with varying percentages (0, 3, 6, 9 and 12%) of the three types of cement namely CEMENT I, CEMENT II and CEMENT III were used in this work. Specimens for the modulus of elasticity were compacted with British Standard Light (BSL) effort and cured for 1, 7, 14, 21 and 28 days. The two types of modulus of elasticity were examined in this study, namely tangent modulus of elasticity (ET) and secant modulus of elasticity (ES). CEMENT I recorded the highest values of modulus of elasticity followed by CEMENT II and then CEMENT III on both tangent and secant. On all the cement types used the values of elasticity increased with increase in cement content and the increments in curing days. The tangent modulus of elasticity tends to be higher than secant modulus of elasticity on every specimen and CEMENT I produced the highest modulus of elasticity. Therefore, this research work proved that the improved samples are adequate for engineering use.
