Study of Strength and Durability of High Volume Fly Ash Concrete with Different Self Curing Agents

High volume fly ash concrete system addresses all the major sustainability issues. It is recommended over the ordinary concrete as it considerably saves cement and also prevents environmental pollution. It is also act as high performance concrete. But if high performance concrete performs smartly without any human care from first day without compromising the good workability, strength and durability then it is said to be smart high performance concrete. This can be achieved by self curing agents which reduces the water evaporations form concrete. In this investigation polyethylene glycol and Spinacia oleracea is use as self curing agent in high volume fly ash concrete to study its effect on workability, strength and durability when internally cured by them. The present paper is focusing on M30 concrete mix with 50 percent fly ash replacement to form high volume fly ash concrete. The optimum dosage of poly ethylene glycol and Spinacia oleracea was taken as 0.5 % and 0.8 % by the weight of the binder. The slump test show it fulfill the medium range workability. Compressive strength of conventionally cured high volume fly ash concrete was less then self cured once and performance for durability of self cured concrete was good for the given conditions.
