Abstract

This project developed and tested protocols to determine concrete curing strength during the construction process, so that building under very cold conditions can be performed safely and quickly. Researchers determined the laboratory strength-maturity correlations for concrete mix designs that ADOT&PF construction teams commonly use. Field tests were conducted in spring and summer of 2009. This study produced a guide, with procedures and computations designed to help ADOT&PF personnel use the maturity method to better estimate the strength of concrete poured on-site.
