Abstract

Finding a self-compacting concrete (SCC) mix side by side with minimizing trial to its cost is the goal of this research. SCC mixes often use large amounts of powder materials, viscosity modifying agents and superplasticizer for creating a very fluid mixture. These fillers explain the reason. So, this experimental study works on partial substitution of cement with different percentages of marble waste powder and pozzolanic material up to 15% and 10% respectively on different seven SCC mixes. Experimental result showed that the best replacement could be up to 20% to get compressive strength above 40 MPa while preserving the viscosity, slump flow, and passing ability due to EFNARC (European Federation of National Associations Representing for Concrete).
