Fly ash is one of the by-products produced from the process of coal burning. Electricity generation using coal as the energy source is the main industry, which produces fly ash as its major solid waste. There are still other types of solid wastes produced from the coal generating plants like bottom ash and gypsum but their volumes are generally far less than that of the fly ash. There are difficulties around the world to achieve effective utilization of fly ash or even to get rid of it. This works particularly existing of analysis of fibre and fly ash concrete in rigit payment. Experimental work was done with 50% replacement of cement by fly ash and fibre use in different percentage 0, 0.2, 0.4, 0.6, 0.8, 1.0, 1.2, 1.4, 1.6 and 1.8 and check the strength properties of fiber reinforced high volume fly ash concrete such as compressive strength, tensile strength, flexural strength and impact strength required for rigid pavements and analysis the resistance of fiber reinforced high volume fly ash concrete and to study the behaviour of fiber reinforced high volume fly ash concrete under central loading, edge loading and comer loading condition. To determine the above properties Concrete cubes of size 150mm x 150mm x 150mm are used to prepare the specimens for determination of compressive strength of FRHV. Compressive strength of FRHVFAC shows an increasing trend up to 1.4% addition of steel fibers. Thereafter compressive strength shows a decreasing trend. The percentage increase of 7 days, 28 days and 90 days compressive strength for 1.4% addition of steel fibers are found to be 17%, 18% and 17% respectively. Tensile strength of FRHVFAC shows an increasing trend up to 1.4% addition of steel fibers. Thereafter tensile strength shows a decreasing trend. The percentage increase of 7 days, 28 days and 90 days tensile strength for 1.4% addition of steel fibers are found to be 38%, 41% and 19% respectively. Flexural strength of FRHVFAC shows an increasing trend up to 1.4% addition of steel fibers. Thereafter flexural strength shows a decreasing trend.
