Establishing a suitable mix design is important to provide the engineering property values necessary for adequate performance of a deep mixing support system. The mix design process often includes a laboratory mixing program to identify suitable binder types and appropriate mixture proportions. The objectives of this research were to investigate: (1) the influences of laboratory procedures and test conditions on measured property values of cement-treated soil, (2) relationships between engineering property values, such as the relationship between unconfined compressive strength and Young's modulus, and (3) the influence of mix design proportions on cured strength and on mixture consistency immediately after mixing.
