Abstract

This paper reports the results of a study conducted to evaluate the influence of natural zeolite (NZ) and blast furnace slag (BFS) and both NZ+BFS on the ultrasonic pulse velocity (UPV), compressive strength, flexure strength and density of concrete. In addition, the relationship between UPV and destructive compressive strength are evaluated. NZ, BFS and both NZ+BFS are used as the mineral admixtures in replacement of portland cement (PC). Compressive strength, flexure strength and UPV were determined at 3, 7, 28 and 90-day. Finally, it was observed that the specimens with BFS 10% and for 90-day had the highest compressive strength and UPV. It was observed that the specimens with BFS 20% and for 90-day had the highest flexure strength. The relationship between UPV and compressive strength was exponential for NZ, BFS and NZ+BFS. The relationship between flexure strength and compressive strength was logarithmic for NZ, BFS and NZ+BFS. However, constants in the experiments were different for each mineral admixture and each level replacement of PC.
