MONITORING OF CONCRETE CURING IN EXTRADOSED BRIDGE SUPPORTED BY NUMERICAL SIMULATION

Abstract

The paper describes a mathematical model of concrete curing taking into account kinetics of setting reactions. The numerical model is implemented in the author’s program that was used to monitor thermal effects recorded in the concrete bottom plate of the extradosed bridge. Numerical approach was verified by experimental measurements and used for assessment of the current compressive strength due to degree of hydration of fresh concrete.
