摘　　要：在混凝土中应用外加剂,要对外加剂和水泥的适应性进行检测、对其掺量进行试配。外加剂的掺入改善了混凝土的微观组成,特别是引气成分引进了大量微小及独立的气泡,使混凝土的含气量增加,提高了混凝土的工作性能和抗渗抗冻性能,增强了混凝土的抗折抗压强度,对提高混凝土的耐久性是非常有效的。A certain of admixture was added to concrete at first to prove an adaptability between the admixtures and cements,and then,the ratios analysis to choose the proper ratio was done.The addition of admixture to the concrete improved the microcompose,escpecially many tiny and segregated bubbles were introduced into the concrete,thus increasing the air in the concrete and improving its workability and freeze thawing resistance and permeability resisting and strength.And it's very efficient to improve the concrete durability.

关 键 词：外加剂 适应性 含气量 强度 耐久性
