Abstract: A novel method and composition of high solid content lime slurry composed of a lime material and water that can be used in stabilization applications. The lime slurry compound itself is chemically treated, by means of a cellulosic or other thixotropic agent(s) and sucrose to create a thixotropic flow property controlled system wherein the wetted lime material remains in suspension, does not settle out prior to use even without further mixing and maintains suitable temperatures without excessive heat build. A novel apparatus and method for mixing the novel lime slurry is disclosed to insure the exact proportioning of all ingredients and the proper wetting of the lime material.

Abstract: A wellbore may be cemented by preparing a cementitious composition comprising water, a metal oxide or hydroxide compound, a phosphate compound, a borate compound, and a sugar, followed by displacing the cementitious composition into the wellbore. The metal oxide or hydroxide compound reacts with the phosphate compound in the wellbore to set into a hard mass. The synergistic effect of the borate compound and the sugar may increase a thickening time of the cementitious composition to in a range of from about 2 hours to about 11 hours at ambient temperatures in the wellbore. As such, the thickening time is sufficient to allow the cementitious composition to be placed in its desired location in the wellbore before setting.

Abstract: Disclosed are formulations adapted to form a foamed cementitious composition, the foamed cementitious composition itself, a method of forming a hydraulic binder foam, and a method of conveying and applying the resulting foam to a substrate. A pumpable cementitious slurry is formed, the slurry is mixed with a gas such as air, and is subjected to mechanically created turbulence to generate gas bubbles and create a foam, which preferably is stabilized by a foam stabilizing agent such as polyvinyl alcohol present in the slurry. The foam is then conveyed to a nozzle or other suitable dispense point from which it is applied, for example sprayed, preferably uniformly, onto a substrate to be coated. Prior to dispensing, a set accelerator is preferably injected, which causes the foam to gel, which in turn improves the hangability of the product on a substrate. The spray material adheres to the substrate and hardens to form an insulative coating on the substrate.

Abstract: Hydrocarbon contaminated soil from the excavation of a leaking underground storage tank is physically and chemically stabilized by combining the soil with a lime substance which is hydrated to form a flowable mixture. This mixture can then be used to fill the excavation and, if applicable, can be flowed around a replaced storage tank creating a low permeable liner. This monolithic mass prohibits hydrocarbons and heavy metals in the soil from leaching into the vicinity groundwater and prohibits leaking from possible future tank ruptures.
