Abstract:Two specific areas of concrete work were identified at the Seabrook Station nuclear power plant where the knowledge of developing concrete strengths could be used to reduce cost and schedule. The Maturity Method for predicting in-situ concrete strength was evaluated under field conditions to establish it as a dependable, practical approach for the Seabrook work. Based on the test results the Maturity Method, utilizing electronic Maturity Meters, was utilized to determine concrete strengths for one application to enable tunnel arch forms to be safely removed in 12 to 14 hours and in another application to reduce winter cure heating by about 30% and shorten curing work by about two days.
