The Effect of Different Curing Conditions on Strength of Concrete Substituted Colemanite

Colemanite 0 %, 1 %, 2 %, 3 %, 4 % and 5 % of the cement were replaced and prepared concrete types were kept under different curing conditions. On the 90 th day, ultrasound pulse velocity and compressive strength tests were performed on the concrete types which were kept under different curing conditions. As a result, the highest strength was obtained with 3% colemanite substitution in all curing conditions while the lowest strength was in the concrete type with 5 % colemanite substitution
