Abstract
Concrete is a composite material containing hydraulic cement, water, coarse aggregate and fine aggregate. The resulting material is a stone like structure which is formed by the chemical reaction of the cement and water. This stone like material is a brittle material which is strong in compression but very weak in tension. This weakness in the concrete makes it to crack under small loads, at tension end. These cracks gradually propagate to the compression end of the member and finally, the member breaks. The formation of creaks in the concrete may also occur due to the drying shrinkage. These cracks are basically micro cracks. These cracks increase in size and magnitude as the time elapses and the finally makes the concrete to fail. The formation of cracks is the main reason for the failure of the concrete. To overcome this and to increase the strength of concrete many attempts have been made. One of the successful and most commonly used methods is providing steel reinforcement. Fiber reinforcement gives the solution for this problem. In this paper we have used steel fibers, The aim of paper is to steel fibers with different curing methods. Our objective is to add the steel fibers of 0.5mm guage diameter to the concrete and to study the strength properties of concrete with the different curing method. i.e., to study the strength properties of concrete (M20 Grade) for fiber content of 5.0% by weight at 7days ,14days and 28days. The compressive strength being studied in our paper. This paper is directed to evaluate effectiveness of different curing methods .Steel Fiber reinforced concrete was prepared with a water-cement ratio of 0.45. The specimens were cast for testing the compressive strength at 7, 14 and 28 days of curing respectively using three curing methods namely Air Drying, Immersion, and Gunny bag curing to cure the specimens until the day of testing and analysis strength. And compare , each other. The overall finding of this paper suggests that concrete should be cured by water curing to attain a better compressive strength but gunny bag and air curing are good results.
