中文摘要：

在水灰比和水泥用量不变的情况下，配制了四种不同含气量的浮石轻骨料混凝土，进行了力学性能试验及抗冻耐久性试验。结果表明：随着含气量的增加，浮石轻骨料混凝土的抗压强度在逐渐减小，抗冻耐久性是先降低后提高。对于四组浮石轻骨料混凝土，抗冻性不仅与含气量有关，还与强度有关。因此，要想提高混凝土的抗冻耐久性，必须加入足够量的引气剂，这样才能保证在混凝土强度下降的同时，抗冻耐久性也能提高。

英文摘要：

The experiment focused on mechanical properties and frost resistance durability of pumice lightweight aggregate concrete with four types of air content in the same water-cement ratio and dosage of cement.The results show that compressive strength of pumice lightweight aggre- gate concrete decreases with the increase of air content,and frost resistance durability decrease firstly and then increase.The frost resistance durability not only was related to air content, but also was related to strength.Therefore it is inevitable to add enough air-entraining agent to improve its frost resistance durability.In this way, frost resistance durability can be increased when strength decrease.
