Mechanical and durability characteristics of marble-powder-based high-strength concrete

Abstract

Concrete is a construction material consisting of cementitious material, fine aggregate, coarse aggregate, and water. Nowadays, the cost of this material is increasing. We need to look for a way to reduce the cost of building materials, especially cement. One of the recent advancements in construction industry is the replacement of cement with waste materials in concrete. This replacement offers cost reduction, energy saving, and protection of the environment. In this study, to achieve the above objectives, an attempt was made to replace cement with the Waste Marble Powder (WMP) produced by the marble industries. The present investigation aimed to study the mechanical and durability properties of High-Strength Concrete (HSC) with cement partially replaced by waste marble powder. Cement was replaced with marble powder at 0%, 5%, 10%, 15%, and 20%. The properties, such as compressive strength, modulus of elasticity, and flexural strength, as well as durability characteristics, such as water absorption, acid resistance, and rapid chloride permeability, of concrete were determined.
