摘要：

This paper presents the results of experimental investigations into the time-dependent ultrasonic pulse velocity (UPV) of concrete containing GGBFS. The UPV was determined at the age of 3, 7, 28, 56, 90, 150 and 180 days for twelve concrete mixes using the prism specimens of plain and GGBFS concrete. The amount of cement replaced by GGBFS was varied from 20% to 60%. The UPV of concrete containing GGBFS has been found to be lower than that of plain concrete for all percentage replacements of cement at all ages and for all the mixes. Relationship between cube and cylinder compressive strength and UPV for GGBFS based concrete has been presented. A new model for time-dependent dynamic modulus of elasticity of concrete containing GGBFS has been proposed. (C) 2012 Elsevier Ltd. All rights reserved.
