Mechanical Properties of Steel Fiber –Waste Marble Aggregate Concrete

Abstract

In this research, the enhancement of compressive, tensile and flexural strength of concrete mixtures was explored using both waste white marble instead of aggregate and steel fibers. White marble was mixed with an ordinary Portland cement replacing the mixture of both coarse and fine aggregate by 10%, 50% and 100% of weight. Besides adding the steel fibres to mixture with a total volume of concrete up to 2%. At the age of 28 days of curing, a significant increase of 24.3%, 34.5% and 38.8% was noticed in compressive, tensile and flexural strengths respectively for the replaced aggregate mixtures. Further improvement was gained by adding the steel fiber.
