• 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.
