Abstract: An improved blend added to soil for soil strengthening and stabilization comprising the combination of 15 to 60 percent by weight of a lime component, such as quicklime, hydrated lime and/or a lime by-product, such as lime kiln dust, with a balance or remainder of cement. The blending of the materials has a synergistic effect, such that the resulting product exceeds the soil strengthening and soil stabilization capabilities of the individual components. The synergistic effect further extends to the hardening and curing characteristics of the blend, in that the blend has a very short hardening time compared with its component parts. The blend physically and chemically modifies the soil to which it is applied to accomplish the soil strengthening and stabilization impacts, and is applicable to a wide range of soil types and conditions.

Abstract: A process for removal of sulfur dioxide from a flue gas. An alkaline admixture is coated with a coating agent that improves dispersability and delays calcination of the alkaline admixture within a combustion zone and results in a coated alkaline admixture. The coated alkaline admixture is introduced to the boiler to create a reaction that reduces the amount of sulfur dioxide from the flue gas.
