THE EFFECTS OF PULVERIZATION ON THE STRENGTH AND DURABILITY OF HIGHLY ACTIVE CLAY SOILS STABILIZED WITH LIME AND PORTLAND CEMENT - SUMMARY. PROCEEDINGS, SOIL STABILIZATION TECHNOLOGY EXCHANGE WORKSHOP, 7-8 NOVEMBER 1989, DENVER, COLORADO

The research reported in this paper explored the effects of the degree of pulverization of a highly active clay soil on the resulting strength and durability to wet-dry tests following stabilization with Portland cement or lime. The addition of Portland cement was found to improve compactability, which led to higher strengths for the materials treated with it. The lime modified heavy clays were found to resist shrink-swell during wet-dry tests much better than the Portland cement treated clays. The overwhelming evidence from this study supports two concepts having to do with the degree of pulverization before stabilization. The finer the pulverization in the field the better the results of soil stabilization, especially for highly active clay soils. In addition, and extremely important, the degrees of pulverization used in the laboratory to establish designs and specifications for field use should be the same as to be utilized in the field.
