The strength and durability of concrete majorly affects due to porosity of concrete. The porosity of concrete can be decreased using selective additive materials to the concrete. In this experimental investigation the magnetic sand has used as an additive to the concrete to reduce the porosity occurred in the concrete. Magnetic sand has been extracted from heap of river sand with the help of magnet and it has been replaced as 10%, 20% and 30% by the replacement of fine aggregate in the concrete. Eventually the strength of magnetic sand replaced concrete have been investigated experimentally by conducting compression strength test, split tensile strength test and flexural test on cubes, cylinders and prisms specimen and the test results have been compared with conventional M20 grade of concrete to estimate the effective utilization of magnetic sand in concrete with effective results.
