Impact resistance of steel fiber-reinforced self-compacting concrete

Among the adopted test methods to evaluate the impact resistance of materials and structural members is the drop-weight impact test. The ACI 544-2R repeated drop-weight impact testing technique was used in this research to evaluate the impact resistance of Self-Compacting Concrete (SCC) reinforced w...
