Abstract
The present paper aims to investigate the properties of cementitious mortars made with industrial wastes. Different portions of cement is substituted by industrial wastes including electric arc furnace dust (EAFD) and red mud (RM) to form various cementitious mortar mixes. Compressive strength, tensile strength, water absorption, and sulfuric acid resistance tests were conducted to investigate the mechanical properties of the mixes. Compressive strength test was carried out at ages 7, 28, and 90 days, tensile strength test was carried out at ages 7 and 28 days, water absorption test was carried out at age of 90 days, and sulfuric acid resistance was carried out at age of 28 days. Results show that tensile strength and sulfuric acid resistance of the mixture with 5% RM substitution is higher than that of the control mixture. Furthermore, water absorption percentage of mixtures with 5% waste substitution was lower than that of control mixture.
