Abstract:

n the concrete industry, an owner buys quality-control specimens but pays for structural members. This practice can be a problem, given that the acceptance criteria may be less concerned with the quality of concrete in the member and more with the strength of the concrete in the quality-control specimen. However, new technologies can close the gap between these separate entities. Maturity has been shown to be an excellent indicator of in-place strength development and quality from fresh to hardened concrete. Match-cure technology harnesses the maturity concept to the curing of quality-control specimens, resulting in quality-control specimens that are representative of the in-place concrete. The match-cure procedure is best applied for release strengths of precast prestressed concrete members. This study summary reports on research, which collected temperature data from precast members in the field and investigated the effect of curing temperatures on the compressive strength, modulus of elasticity, and permeability.
