Utilization of Marble Powder, Bagasse Ash, and Wood Waste ash in Sustainable High-Performance Concrete

Abstract

Concrete is a largely used material for construction in the modern world. The concrete demand is being increased continuously due to rising demand in industrialization and urbanization. Therefore, a bulk number of raw materials is required for concrete production. In this study, Sugarcane Bagasse Ash (SCBA), Wood Waste Ash (WWA), and Marble Powder (MP) are used as supplementary cementitious materials in concrete and their modulus of elasticity, compressive strength, modulus of rupture, tensile strength, drying shrinkage, and water absorption is determined and compared. Consistency of cement, as well as cement plus waste, is calculated to determine the water demand of the wastes. The specific gravity of the waste materials and sieve analysis of fine and coarse aggregate is done and their fineness modulus is determined. Test results show that SCBA shows better results. The water demand of SCBA is the least and it gives maximum compressive strength. The water demand of WWA is highest and it gives minimum compressive strength. By replacing 25% BA in cement concrete the compressive strength reduces up to 40% and with 25% WWA it reduces up to 48%. The Mix Proportioning in the current research was conducted under the guidelines outlined in ACI 211-1. In the first phase, the concrete mixes were prepared by using 100% of cement content as binding material in concrete and were referred to as CC (control mix). In the second phase, 3 different concrete mix proportions were prepared by using 25% of marble powder, bagasse ash, and WWA as partial substitution of cement in concrete and represented by SCBA-25, WWA-25, and MP-25 respectively. Workability was placed constant of 25 mm throughout the study. Then cube (100mm x 100mm x 100mm) specimens were prepared to investigate the average CS of concrete specimens at different ages. The results of the compressive strength test revealed that the bagasse ash and wood waste ash concrete samples exhibited superior performance compared to all other materials, surpassing even the conventional concrete samples at 90 days of age.
