Effect of the vinyldene chloride emulsion curing agent on the plastic shrinkage cracking properties of the cement mortar

摘要

In this paper, the effect of the membrane of the vinylidene chloride emulsion on the plastic shrinkage cracking properties of the cement mortar in different ambient tmeperature, solid conetne of the vinylidene chloride emulsion and coating procedure were ivnestigated according to the accelerating aging method. there is an obvious anti plastic shrinkage effect when the cement mortar panel panel was coated with the vinylidene chloride emulsion comparing with the control one. In the case of htecoating method, the effect of painting on the plastic shrinkage cracking resistance is better than that of spraying. Te higher the temperature, the lower the effect of the vinylidence chloride emulsion on the plastic shrinkage cracking resistnace.
