Compressed cement-soil block is known as low cost building materials. This paper studies the effects of soil grading and the characteristics of soil on the properties of compressed cement-soil such as compressive strength, dry density and water absorption. Compacting pressure of 10 MPa and 30% binder with respect to cement content of 10% were used. The results obtained from crushed soil particles were better than those from natural soil. Mixture of 35% soil and 65% sand produced the optimum of strength, dry density and water absorption. Strength and dry density increased with the fineness of soil particles. Moreover, soil properties also affect the strength properties of cement-soil. Its strength is significantly reduced with increasing plasticity index or liquid limit.
