Title:
METHOD FOR PRODUCING GROUT CONTAINING CEMENT MILK AND METHOD FOR INJECTING GROUT
Document Type and Number:
Japanese Patent JP2017088674
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a grout in which curing time is elongated, also the settling of cement grains is reduced, and pressure-feeding is facilitated by suppressing the hydration reaction of cement.SOLUTION: Provided is a grout containing cement milk comprising cement, soluble condensed sodium phosphate, and water in which the surfaces of the cement particles and the space between the cement grains are involved or covered with cotton-like insoluble white condensed calcium phosphate generated by the reaction between calcium hydroxide eluted from the cement and the soluble condensed sodium phosphate, thus hydration reaction and the settling of the cement particles are suppressed.SELECTED DRAWING: None
