description | Non-destructive evaluation using ultrasonic pulse velocity (V(p)) testing has extensive applications in the concrete industry. With advances in construction technology, the use of ground granulated blast furnace slag (GGBFS) as a partial replacement to cement in a concrete mix is growing in popularity primarily because it reduces the initial capital cost of raw materials and the associated energy costs. This paper investigates the effect of the water-to-cement (w(c)) ratio and the cement content replaced by GGBFS on the development with time of the ultimate compressive strength ([Formula: see text]) and the compression wave velocity (V(p)) of mortar. The results showed that in the case of mortar with higher percentages of GGBFS replacement (where nucleation surfaces are more abundant), increasing w(c) can increase [Formula: see text] but cause a decrease in V(p). The posterior hydration process is highly dependent upon the water particles in the mixture after the first stage of hydration. After 7 days of curing, experimental results show that the [Formula: see text] of slag blended cement mix design w(c) ratio of 0.6 surpassed the [Formula: see text] value of an Ordinary Portland cement. A regression model correlating the [Formula: see text] and V(p) of slag blended mortar is developed, which can be used to predict [Formula: see text] at concrete ages ranging from 1 day to 28 days for mixes with GGBFS percentage replacement values ranging from 15% to 45%. |
