An Empirical Model to Predict the Strength of Cement Stabilized Lateritic Soil
An Empirical Model to Predict the Strength of Cement Stabilized Lateritic Soil
Lateritic soils when stabilized with cement to create Cement Stabilized Lateritic Soil (CSLS) can be used in place of crushed rock as base course. CSLS use, however, requires a mix design. In order to reduce the time and effort required for the design, a mathematical model may be used to facilitate the initial prediction of cement content (CC) and strength. This study seeks to develop empirical equations to predict the UCS at any CC for any curing age. To develop the equations, samples of a lateritic soil for CSLS were airdried and characterized. Then CSLS at different CC ranging from 2% to 8% were prepared. For each CC, CSLS samples were prepared at the respective optimum moisture contents and cured for 4, 11, 18 and 32 days after which the UCS was determined. The results were analyzed to develop empirical equations to compute the UCS for given CC and AGE
