Crack reducing admixture for cementitious compositions
A cementitious composition including at least one cementitious material and at least one crack reducing admixture including: (i) from 0 to about 5 weight percent of at least one alcohol, based on the total weight of the admixture excluding water; and (ii) a compound having the chemical structure of formula (III): wherein: v is an integer from 0 to 50 and w is an integer from 0 to 50, with the proviso that the sum of v and w is at least 1 but not greater than 50. Also, methods of making the cementitious composition, reducing or eliminating the formation of cracks in a cementitious composition as the cementitious composition cures, and limiting the size of cracks which form in a cementitious composition as the cementitious composition cures using an admixture for cementitious compositions as described herein.
