Analysis of Properties of Mix Design Concrete using Steel Scrap

The aim of the paper was to study the feasibility of using steel scrap in mix design concrete by checking various concrete parameters like compressive strength, tensile strength and flexural strength. All the parameters checked with varying percentage by 0%, 0.5%, 1%, 1.5% and 2% by weight of concrete. In this experimental study M 30 grade concrete is used. For this concrete cubes, beams and cylinders were casted. Total 45 concrete specimens were casted and cured. Tests were done on cured concrete specimens at 28th day. The tests performed were compressive strength test, split tensile strength test and flexural strength test by following the guidelines set by Indian Standard. The test results were compared with plain cement concrete. The compressive strength of M-30 grade concrete was found out to be 33.25 N/mm2, 36.00 N/mm2, 38.36 N/mm2, 34.59 N/mm2 and 32.51 N/mm2. The split tensile strength was 2.78 N/mm2, 2.91 N/mm2, 3.52 N/mm2, 3.16 N/mm2 and 2.84 N/mm2. The flexural strength was 4.43 N/mm2, 4.44 N/mm2, 4.48 N/mm2, 5.34 N/mm2, and 4.33 N/mm2 respectively steel scrap percentages. After comparing results, we know that the 28 days compressive strength, split tensile strength and flexural strength of steel scrap concrete is more than plain cement concrete.
