Abstract

Concrete is a majorly used construction material which gives both good strength and durability to the structures constructed. Good strength of the concrete is achieved by the process of curing. Curing requires large amount of water. If the curing is not sufficient, water evaporates and hydration stops in the concrete. It causes cracking and low compressive strength of concrete. To reduce this effect self-curing concrete is used. It reduces the crack and shrinkage that occur in the concrete. In our project cement is partially replaced by GGBS. The GGBS is added at 20% of weight of cement. The polyethylene glycol is used as a curing agent. It is added in the concrete at 0.5%, 1%, 1.5% by weight of cement. To enhance the property of curing glass fiber is also added. The fiber is added at a rate of 1.75% of the volume of the concrete. The mixing design is done through the IS methods. The grade of concrete is M40. The following results of the conducted tests like split tensile test, compressive strength test, flexural strength test were computed in the laboratory at an interval of 7, 14, 28 days of internal curing.
