Mud slurry composition


PURPOSE: The titled composition, obtained by incorporating an aqueous slurry consisting of mud and a hydraulic setting component with a specific high polymer, capable of improving remarkably the dispersibility and fluidity and further the operability and quality of the solidified material, and suitable for underground continuous wall construction and weak ground improvement work, etc. CONSTITUTION: A composition obtained by incorporating an aqueous slurry consisting of (A) mud, e.g. bentonite, and (B) a hydraulic setting component, e.g. Portland cement, with (C) a water-soluble polycarboxylic acid salt. The above- mentioned polycarboxylic acid salt is preferably for example a polymer of an α,β-unsaturated carboxylic acid salt monomer or a water-soluble salt of a copolymer thereof with an ethylenically unsaturated monomer, etc., etc., and the number average molecular weight is preferably 1,000W25,000. The amount thereof to be incorporated is preferably 0.05W3.0wt% based on the component (B). COPYRIGHT: (C)1985,JPO&Japio
