Flexural Analysis of Concrete Specimens with Substantial Substitution of Cement by Marble Dust and Scrap Rubber as Fibre
Abstract: Concrete is a crucial material in building and construction. Concrete is becoming more and more in demand every day. Concrete's essential ingredients are running out, therefore we need to find replacements. In addition to providing the necessary strength to the concrete, the replacement materials should also have the properties of the genuine components used in concrete. Typically, compression is where concrete shines, whereas tension and shear are where it falters. …
