Abstract:In this paper the equipment was designed and developed by ourselves and early-age frozen-heave stress of control concrete at subzero temperature was measured at the frozen temperature of-5℃,-10℃ and-15℃.The effect of the early-age frozen-heave stress of the concrete on the compressive strength and durability at subzero temperature was studied.
Keywords:durability  frozen-heave stress  anti-freezing agent  air-entraining agent
