Cracking in Soil Cement: Cause, Effect, Control

Abstract

The primary causes of cracking in soil cement are high moisture content, fine-grained soils, low densities, and inadequate curing. These factors relate to drying and attendant volume changes, which lead to shrinking and cracking. This article discusses in depth the cause, effect, and control of cracking in soil cement. It also recommends the use of soil cement for its good properties: 1) it is strong and economical, 2) it does not rut, 3) it permits thin surfaces thereby minimizing surface rutting, 4) its deflections are low, and 5) it minimizes subgrade pressures without undue emphasis on cracking.
