Mica stabilization with lime, portland cement and lime-calcium carbonate
Research was conducted to study the unconfined compressive strength of a mica soil stabilized with various percentages of lime, Portland cement, and combinations of calcium hydroxide and calcium carbonate. In order to trace the calcium carbonate and calcium hydroxide in the stabilized soil, x-ray …

Stabilization of non-plastic soils with calcium hydroxide-calcium carbonate mixtures
… It was found that carbonate generally increased unconfined compressive strength and secant modulus of elasticity when included as part of the lime stabilizing agent. This effect was most pronounced with soils with a large sand content and low mioa content. A calcium hydroxide-calcium carbonate …

Impact of Jet Grouting on the Lateral Strength of Soil Surrounding Driven Pile Foundations
Jet grouting was used to strengthen the soft soil surrounding the piles and the pile cap of two full-scale driven pile foundations. Soilcrete columns, created by jet grouting, were placed underneath the pile cap and surrounding the piles of the first foundation. Two rows of soilcrete columns were …
