Reducing Concrete Cure Times Based on a Quantitative Assessment of Resistivity and Porosity

Curing, which is typically done after concrete placement, is primarily responsible for maintaining the desired moisture and temperature conditions in the bulk of concrete for maximum hydration. Maximum hydration, in turn, leads to reduced porosity, which directly affects strength and durability. Given the importance of curing, several practical and useful guidelines have been published over the years. The objective of this research project is to optimize and potentially reduce concrete cure times by aiming for a certain level of porosity for each specific concrete member. This is only possible if porosity is quantified in a reliable manner.
