| 摘 要： | 自行设计与研制了测量混凝土早期冻胀应力的设备,并通过该设备测量出了不同配比(不同水灰比,掺加防冻剂、引气剂,掺加粉煤灰和矿渣粉)混凝土早期冻后产生冻胀应力的规律;并探讨了不同受冻制度(标养6h后受冻和标养达到其28d强度的30%两种制度)对混凝土抗压强度及抗折强度的影响。

| Abstract: | In this paper,the equipment was designed and developed by ourselves and the regularity of early-age frozen-heave stress of different proportions concrete at subzero temperature was measured(different w/c,anti-freezing agent and air-entraining,fly ash and slag).The effect of different freezing model on concrete compressive strength and tensile strength(specimen frozen after hours in chamber and frozen after their compressive strength achieve 30 percent of 28d strength)is studied. |

| Keywords: | frozen-heave stress compressive strength tensile strength |
