Freeze-Thaw Damage Model for Different Types of Concrete
Abstract:
Common concrete, lightweight aggregate concrete and self-compacting concrete with strength grade C50 were tested under freeze-thaw actions. Experimental results show that the Light weight aggregate concrete has the best freeze-thaw resistance. Furthermore, the relative dynamic elastic modulus is used to quantitatively analyze the interior damage of concrete materials subjected to freeze-thaw actions, and the freeze-thaw damage evolution equations were established by using quadratic functions, and the computational damage values agree well with the experimental results.
