Abstract
This study investigates the possibility of utilizing the waste rock powder as a supplemental material for cement stabilization of soft clay ground. The results of the study are summarized as follows: (1) there is an optimum mixing proportion of the waste rock powder for the cement stabilization, (2) the unconfined compressive strength varies in inverse to the ratio of designed water content to cement content, (3) the unconfined compressive strength has the highest value in every case when the waste rock powder and cement are mixed with the soft clay at a designed water content around 1.2 times the plastic limit, (4) the corresponding content of waste rock powder and cement can be estimated upon the previously selected value of designed water content, (5) the optimum content of waste rock powder and cement can be decided for various values of the water content of clay using the experimental equations.
