Temperature Time Factor

Posted by Adrian Field on October 31, 2013

Temperature Time Factor (TTF) calculations and compressive strength results are used for estimating concrete strength gain using the maturity method as outlined in ASTM C 1074. To develop the data used for this type of evaluation, cylinders are cast to be broken at certain intervals. The total curing time in either days or hours and
