Title:
PRODUCTION OF CEMENT-BENTONITE INJECTION LIQUID AND POWDER FOR PRODUCING THE SAME INJECTION LIQUID
Document Type and Number:
Japanese Patent JPH0543283
Kind Code:
A
Abstract:

PURPOSE: To obtain cement-bentonite injection liquid by a producing method in which a complex liquid stage is easily controlled by simultaneously mixing cement powder, bentonite powder and water at the specified weight ratio and simultaneously mixing a complex liquid.

CONSTITUTION: Cement powder and bentonite powder are prepared so that weight ratio is 100:10-300 and total is regulated to 100 pts. wt. Cement-bentonite injection liquid is obtained by simultaneously adding 100 pts.wt. both powder in total to 50-500 pts.wt. water and mixing this mixture. Further both cement powder and bentonite powder are mixed at weight ratio of 100:10-300. Powder for producing the cement-bentonite injection liquid is produced by using this mixture as a main agent and blending a thickner (e.g. vinyl acetate-ethylene copolymer) and a dispersant (e.g. lignin sulfonate) in accordance with necessity. The producing time of cement-bentonite injection liquid is shortened by using this powder.
