NON-DESTRUCTIVE EVALUATION OF FLOWING CONCRETES INCORPORATING QUARRY WASTE

Flowing concretes were produced using quarry waste as a partial replacement of natural mining sand. The non-destructive properties such as dynamic modulus of elasticity, ultrasonic pulse velocity, and initial surface absorption were investigated. The slump, slump flow, V-funnel flow, air content and compressive strength of the concretes were also determined. The variations of dynamic modulus of elasticity, ultrasonic pulse velocity, and initial surface absorption with compressive strength were observed. In addition, the relationship of the aforementioned non-destructive properties was examined. Test results indicate that quarry waste did not significantly affect the non-destructive properties of the concretes except initial surface absorption. Dynamic modulus of elasticity, ultrasonic pulse velocity, and initial surface absorption varied linearly with compressive strength. Moreover, dynamic modulus of elasticity and ultrasonic pulse velocity were well-correlated.
