Ultrasonic pulse velocity—compressive strength relationship for portland cement mortars cured at different conditions

摘要: The purpose of this paper is to establish some correlations between the main technical parameter with regard cement-based materials technology, 28-day compressive strength, and ultrasonic pulse velocity standard mortar samples cured at three different conditions—(i) under water 22 °C; (ii) climatic chamber 95% RH (iii) lab ambient, 50% RH, °C—and after five curing periods 1, 2, 7, 14, 28 days. Good for each conditions were obtained. All positive linear relationships showed better R2 than exponential ones. These findings may promote use estimation strength Portland cement within factory internal quality control.
