Resistance to freezing and thawing 抗冻融性39
Through manipulating the air content of mixture to control concrete frost resistance is the universal method in projects , but the study on the effect of concrete pore structure change after air entraining to the concrete frost resistance and impermeability is few , the study on the effect of mineral additive to concrete pore structure and durability is even fewer , so carry on this aspect research has significant meaning 通过控制拌合物的含气量来控制混凝土的抗冻融性,是目前工程中普遍采用的方法,但引气后混凝土的孔结构变化及其对抗冻、抗渗等耐久性的影响研究较少,而无机盐类外加剂对混凝土孔结构及其耐久性影响的研究更少,因此开展这方面的研究具有重要意义。
