Experimental Asymptotic analysis of Fibrous Self-Curing Concrete exposed to Acid and Salt attack

Abstract

Self-curing concrete is one of the special concretes in mitigating insufficient curing disorder due to human negligence and paucity of water in arid areas, inaccessibility of structures in difficult terrains and in areas where the presence of fluorides in water will badly affect the characteristics of concrete. The use of super absorbent polymer (SAP) in concrete helps in self-curing and thus better hydration of cement Is achieved. Present study involves the effect of SAP and fibre on durability aspects. The grade of concrete selected was M40. It was found that SAP could help in self curing by giving strength on par with conventional curing. The dosage of SAP Is 03% by weight of cement and polypropylene fibre (PPP) varying from (0.1%-0.50/) by the volume fraction of concrete. Experimental investigation is about Acid attack, Sulphate attack and Corrosion resistance of Self-Curing Concrete (SCC) and Fibrous Self-Curing Concrete (FSCC).Self-curing concrete is one of the special concretes in mitigating insufficient curing disorder due to human negligence and paucity of water in arid areas, inaccessibility of structures in difficult terrains and in areas where the presence of fluorides in water will badly affect the characteristics of concrete.
