Abstract: This work used electrical resistivity over the first 72 h of hydration to measure the impact of air, sealed, and wet curing on mortar samples at different depths. The resistivity measurements provide new insights that ...

Abstract: The apparent diffusion coefficient (Dic) is important for modeling the service life of concrete. Most diffusion-based tests require the sample to be ponded for at least 28 days, and significant labor is required to ...

Abstract: Contractors are interested in removing and reusing the formwork from concrete walls as soon as possible to speed up construction. While the concrete may have sufficient strength, there is little information about the impact ...

Abstract: Widespread gradations of aggregates have been blended together to produce concrete mixtures with adequate performance; yet, poor performance of some of the concrete mixtures has been instigated by certain gradation ...

Abstract: A key parameter in concrete is the water-to-cementitious ratio (w/cm). Unfortunately, it can be difficult to ensure the w/cm of a concrete mixture is within the specified limit(s) in either fresh or hardened concrete. An ...
