STUDY THE EFFECT OF STONE DUST & STEEL FIBRE ON STRENGTH PROPERTIES OF CONCRETE

Nowadays, there's associate increasing interest within the development of ecofriendly materials. The properties of Stone dust and Sand are almost same so it can be easily used as partial replacement of sand in concrete . Steel Fiber is also added to the concrete that it increases the crack resistance, ductility, energy absorption or toughness of concrete. Thus, this paper addresses the results of change of Stone dust and Steel fiber on the strength properties of concrete. The replacements are done at 0%, (30%, 1%), (40%, 1%), (50%, 1%) of fine aggregate with Stone dust and addition of Steel fiber 1% by the weight of cement. Design mix is prepared on M30 grade of concrete. The result showed that at fixed W/C ratio (0.40) the strength and durability increased initially at small percentages and the cost for production is also cheaper
