Abstract:
Laboratory experiments are reported with the intention to show the effects of epoxy modification of portland cement mortars in the presence or absence of accelerating and/or plastifying admixtures. . .The test results show considerable improvements in the workability of the epoxy-modified mortars, and strength increases, when it accelerating admixture was also used, up to 100 to 120%. It appears from the results of the silylation that these strength increases were caused mostly by physical factors.
