Experimental Research on Hydration Heat Temperature of Concrete Box Girder in Low-Temperature Environment

Abstract:

The temperature stress is one of the main reasons for early age cracking of concrete under low temperatures,it has the actual value of reference for the design and construction of concrete structures to study the regularities of hydration heat temperature of concrete box girder in low-temperature environment. Therefore, through the test of concrete box girder hydration heat temperature, this paper analyses the temp-time curves of temperature of the concrete box-bridge cross section. The results can be used for concrete temperature control and/or cracking control of box girder in similar environmental area.
