Abstract

This study investigated the durability of Type I and Type IP cement concrete. Specifically on the effect of varying water-to-cement ratio and curing period and was assessed through the sorptivity test. Sorptivity testing is a standard test used to measure water transport into an unsaturated sample. Initial sorptivity of concrete may be used in evaluating the durability of concrete structures which are not often exposed to water while he secondary sorptivity may be used for concrete structures which are in constant contact with water. The results showed that Type IP cement concretes yield higher initial sorptivity values. In the case of the secondary sorptivity, there is a very small difference between the two types of cement concretes. The result of the statistical test for secondary sorptivity indicated that the type of cement has no significant effect on the water absorption of concretes. Furthermore, lower sorptivity was achieved in specimens with low water-to=-cement ratio and long curing periods.
