Abstract
Abstract Concrete is huge construction material which is used all over the world. In globally, around 7% of CO2 is released from the cement industry during manufacturing. This highly affects the earth’s environment and depletes the natural resources. So there is a necessary to develop an alternate material of cement in the construction industry. In this work, fly-ash is partially replaced with cement as a binder. The physical properties of fly-ash have determined. The strength of the concrete varies with the addition of fibers and the admixtures. In this work, various types of fibers are used to evaluate the strength properties and are Steel fibers, polypropylene and basalt fibers. The strength parameters are determined with the different percentages of the fiber used in the concrete along with the fly-ash at a curing period of 7 and 28 days at a room temperature. The main aim of this paper is to know the crack analysis of a construction when the fibers were used in the concrete. T-beam section was considered with different proportions of fibers for the crack analysis. The ultimate load and the deflection of the T-beam was observed at 0.6% of steel fiber, 0.3% of basalt fiber and 0.1% of polypropylene with an ultimate crack load of 48KN and the maximum deflection of 62.27 mm.
