Abstract
This paper aims to predict the modulus of elasticity Ec of high-strength concrete (HSC) under different in situ curing conditions. Because of the effect of the hydration temperature and the curing condition, the Ec value of HSC measured on moist-cured specimens may not be able to sufficiently represent that of HSC in structures and precast concrete components. This issue is not adequately taken into account in current codes of practice. Equations based on moist-cured specimens may result in a large discrepancy when used to estimate the in situ Ec of HSC. In this study, measured Ec of HSC on member-cured, temperature match–cured, on-site-cured specimens, and drilled cores from large structural members are gathered. The accuracy of selected equations is investigated using the collected data. Based on the investigations, new empirical relations for estimating the Ec of HSC considering the effect of the in situ curing conditions are proposed.
