Abstract:Problem:
The process of waiting for concrete to attain its desired strength for certain
construction applications can pose one of two problems. The concrete strength
may be overestimated, which creates a safety concern for workers and the general
public. The concrete strength may also be underestimated, which incurs costs
because of delays due to the curing of the concrete. The maturity method was
viewed as a viable option for determining concrete strength, since it requires only
the concrete’s temperature history to estimate in-place strength.
Objectives:
The research objectives were to use a wireless maturity meter on a newly
constructed bridge in the state of Maryland, to use the maturity method to estimate
compressive strengths during curing of freshly placed State Mix Six concrete, and
to establish a protocol for the application of the maturity method in Maryland.
