Abstract
Curing is the process of controlling the rate and extent of moisture loss from concrete during cement hydration. It may be either after it has been placed in position or during the manufacture of concrete products. Good curing is not practically possible in most of the cases. The self-curing concrete means that no external curing required for concrete. Self-curing provides an internal water reservoir throughout the concrete, so that it is more readily available to maintain saturation of the cement paste during hydration, avoiding self-desiccation (in the paste) and reducing autogenous shrinkage. The grade of concrete selected was M30. Self-curing is done by Super Absorbent Polymer (SAP). The effect of variation in strength properties were studied for different dosage of self-curing agent (0.1% – 0.5% weight of cement) steel fiber (1%, 1.5%, 2%) and compared with fly ash concrete. By compression test optimum percentage of SAP is found as 0.3 and steel fiber is 1.5.
