通过试验研究，证明引气剂可以改善水工混凝土的和易性，适量掺入引气剂可提高混凝土的坍落度，降低混凝土的泌水量，提高混凝土的抗冻等级，但抗压强度会降低。引气剂的掺加使混凝土氯离子渗透系数明显降低，抗渗性能提高。

Experimental studies prove that air-entraining agents can improve the workability of hydraulic concrete.The slump of concrete can be increased by suitably adding air-entraining agents,thereby lowering the water secretion of concrete,and improving the frost-resistant level of concrete,but the compression strength will be reduced.Addition of air-entraining agent prominently reduces concrete chloride ion permeability coefficient and improve impermeability.
