Abstract
This invention discloses a high rate, cement slurry mixing system and method which produces a highly dispersed slurry with the lowest possible viscosity in respect to the water cement ratio and the type and amount of chemical dispersant used in the slurry formulation. The slurry so produced is used in soil-cement construction operations and has the advantage of delayed hydration to allow reasonable time for slurry transport, spreading, intermixing with the soil, plus time for grading, shaping and compaction before a significant amount of cement hydration (setting) occurs.
