Experimental Study on Self Curing Fibre Reinforced Concrete using Monofilament and Fibrillated Polypropylene Fibre

S. M. Kavitha, Dhivyalakshmi G

Abstract


Construction industry is one of the fastest emerging industries around the world. Self curing of concrete meet the demand of water by reducing the amount of water required for curing of concrete. Concrete attains its strength by proper curing if there is any negligence in curing it causes adverse effects in concrete strength and its durability. The proper curing is done by adding self curing agent PEG 400 which provides better curing and also enhances the strength of the concrete. Crack formation is one of the major problems in concrete structures which can be overcome by adding fibres. The detailed experimental work is carried out by varying the dosages of PEG 400 by 0.5%, 1.0% and 1.5% by weight of cement and thus by keeping the percentage of monofilament and fibrillated polypropylene fibre by 1% by weight of cement for M30 grade concrete in order to study its strength characteristics. The 1% PEG 400 is optimized for both monofilament and fibrillated polypropylene fibres.
