Description
Summary:Curing is the most significant aspect for concrete strength and durability. In some instances, such as when there is a lack of rainfall or bad weather conditions, improper curing happens. As a result, self-curing process is used to solve this problem. This experiment investigated at the performance of self-curing agents in mortar cubes. Self-curing substances such as coir pith, Spinacia oleracea, and PEG 400 were utilized in this experimental work. First, the coir pith was partially replaced for fine aggregate in mortar cubes in varying percentage of 1%, 2% and 3% as a self-curing agent. The water absorbed earlier by coir pith will be utilized during cement hydration process and reduces shrinkage. The second step involves the usage of Spinacia oleracea extract in 0.6%, 0.8%, 1.0%, which was partially substituted for cement and act as a self-curing agent. Similarly, PEG 400 in 1%, 1.5%, 2% was partially replaced with cement and utilized as self-curing agent. The mechanical and durability features of mortar containing self-curing agents were investigated and compared to those of ordinary mortar. The results reveal that natural self-curing agents outperformed chemical self-curing agent.
