Experimental Study on Strength and Durability Characteristics of Fibre Reinforced Recycled Aggregate Concrete using Artificial Sand

This research work is done to obtain different properties of fibre reinforced recycled aggregate concrete using artificial sand, and to find the optimum percentage replacement of recycled coarse aggregate in concrete with constant 50% replacement of river sand by artificial sand in addition with 1.5% steel fibres, further to compare the properties of conventional concrete with fibre reinforced recycled aggregate concrete using artificial sand. To carry out this experimental work the specimens were casted using different percentage replacement of recycled coarse aggregate i.e. (0%, 20%, 40%, 60%, 80% and 100%) with constant 50% replacement of river sand by artificial sand in addition with 1.5% steel fibres. And results shows that recycled coarse aggregate can be replaced up to 40% for production of M30 grade concrete with constant 50% replacement of river sand by artificial sand in addition with 1.5% steel fibres, and it is observed that the strength of concrete is reducing with increase in replacement percentage of recycled coarse aggregate with constant 50% replacement of river sand by artificial sand in addition with 1.5% steel fibres, however strength achieved by conventional concrete is less than the strength achieved by concrete which is produced with 100% replacement of recycled coarse aggregate by natural coarse aggregate with constant 50% replacement of river sand by artificial sand in addition with 1.5% steel fibres. By using this we can produced green concrete, sustainable concrete or ecofriendly concrete by using artificial sand as fine aggregate and replacement of natural coarse aggregate by recycled coarse aggregate in a concrete.
