Abstract:

This study consisted of an examination of the compressive strengths of soil-cement mixtures on 15 construction projects from the standpoint of design and actual achievement. The laboratory design test was examined closely along with the present field method of density control for soil-cement bases and the distribution of cement within the bases.

the examination of the laboratory design test showed inconsistencies, inherent in the procedure, existed in the laboratory design method; therefore, additional controls were established in the testing procedure. In addition, a new cement recommendation system was developed and implemented.

Field investigation indicated that, based on compressive strength, the quality of the soil-cement bases varies greatly both within an individual project and between different projects. Under the present construction techniques of cement application, and moisture control, it was found that 75 percent of the construction projects checked achieved 75 percent (225 psi) of the laboratory design strength (300 psi) at 28 days. Using the present method of controlling densities there is an implication of greater degree of compaction than actually achieved. Determination of cement contents of in-place mixed soil-cement bases indicated large variation within the bases and from the design percentages.
