Application and Research of Latex Tenacity Cement Slurry System

摘要

This article presents the stability research of latex tenacityrncement slurry, develops the BCT series stabilizer and studiesrnthe performance of the slurry and the set cement. Due to thernslurry performance study, it is found the latex material can bernevenly distributed in the slurry, which can form a film to bondrnfree water and micro particle, reduce fluid loss and prevent gasrnmigration. Adding other additives to this system, the slurryrnshows better performance with lower fluid loss, betterrnrheological behavior and adjusting thickening time. Due to thernset cement performance study, it is found the latex particle canrnevenly fill in the fine gap of C-S-H gel. It assembles and formsrna film to cover the CSH surface, which can decrease the setrncement elasticity coefficient and permeability, improve itsrnimpact resistance and anticorrosive properties. Moreover, thernapplication of this latex tenacity cement slurry system isrnintroduced in this article.
