The superplasticizer for high intensity soil cement slurry manufacturing which

摘要

PROBLEM TO BE SOLVED: To provide a fluidizing agent for preparing a high strength soil cement slurry, which is capable of imparting a high fluidity to the prepared soil cement slurry, even if an injection ratio of cement milk into soil is reduced so as to suppress production of construction sludge to be discarded, and is capable of yielding a high-strength cured product from the prepared soil cement slurry, particularly a high-strength cured product achieving a uniaxial compressive strength of 10 N/mm² at material age of 28 days.;SOLUTION: The fluidizing agent for preparing high strength soil cement slurry comprises: 60-98 mass% of a specific water-soluble vinyl copolymer having specific two kinds of constitutional units at a specific ratio in the molecule; and 2-40 mass% of a polyalkylene oxide adduct of a specific lower mono-alcohol (100 mass% in total).;COPYRIGHT: (C)2012,JPO&INPIT
