Cement Stabilisation an overview ScienceDirect Topics

Walker (1995) has suggested that, as a measure of durability, the wet/dry strength ratio is likely to be approximate at best and certainly no substitute for real testing owing to the inherent variability of the material. Both the dry and saturated strength of cement stabilised soil blocks was improved with increased cement content and reduced

Cement-Stabilized Soil an overview ScienceDirect Topics

Lime-stabilized clay and Portland cement-stabilized sand are two examples. The chemical stabilizers, normally added at a 2 to 10% rate, increase soil internal cohesion via chemical bonding. Chemically-stabilized soils, which are stiffer and stronger than the unreinforced soils, also exhibit tensile cracking as a major mode of failure.

Soil stabilization with cement and affect the cement

Soil stabilization with cement. The process of cement stabilization can be done by mixing the portland cement and pulverized soil with water and compacting the mix to attain a strong material. The material takes place y mixing soil and cement is known as soil-cement. The material becomes hard and durable structural material as the cement hydrates and develops strength.
