Influence of Stone Quarry Dust and Jute Fibre on the Mechanical Properties of Concrete

Abstract

In the present era, concrete is one of the extensively used construction materials. Enormous efforts are made to improve the tensile strength of concrete due to its weakness in tension. In this paper, an attempt is made to enhance the tensile strength of concrete by introducing jute fiber in concrete. Waste from the crushing plants is used as a replacement of fine aggregates to achieve good compressive strength and jute fiber is added to enhance tensile strength. The length of the jute fiber used is 25mm and the percentage taken was 0.25%, 0.5% and 0.75% of the volume of concrete. Stone quarry dust is replaced as 10%, 20%, 30% and 40% of the weight of fine aggregates. The compressive test split tensile test and the flexural test is performed at 7, 14 and 28 days by casting cubes, cylinders, and beams for the respective tests. Experimental test under a controlled environment revealed that stone quarry dust raised 13% compressive strength at 28 days and jute fiber raised 21.15% tensile strength at 28 days. Further investigation is carried out by introducing both stone quarry dust and jute fiber into the concrete and optimal results are discussed. Final test exposed that amalgamation of jute fiber and stone quarry dust imposed a positive impact on compressive, split tensile and flexural strength of concrete.
