An Experimental Analysis on the Strength by Using Marble Dust and Rural Waste Fibers

Experiments were conducted on concrete cubes with various percentages of marble dust and fibers as Cement. When the cement is replaced with 8% marble powder gives the optimum compressive strength. The steel fiber reinforced concrete gives 21.22% compressive strength increase with addition of 1% steel fiber with 8% of marble powder volume of concrete with compared with normal mix. The nylon fiber reinforced concrete gives 11.79% compressive strength increase with addition of 0.75% nylon fiber with 8% of marble powder volume of concrete with compared with normal mix. The jute fiber reinforced concrete gives 8.59% compressive strength increase with addition of 0.75% jute fiber with 8% of marble powder volume of concrete with compared with normal mix. So by the above observation a saving 5.69% in the cost of cement can be achieved by using steel fiber, 6.6% using nylon and 9.02% total cost saving in the concrete. The percentage of increase compared with control concrete for M20 respectively.
