针对普通道面混凝土施工和易性不易控制、强度储备偏低、耐久性不良等现象,通过掺加引气减水剂,配制高性能道面混凝土。室内试验和现场应用效果均表明:与普通道面混凝土相比,掺引气减水剂的高性能道面混凝土施工方便,匀质性好,强度、抗冻和耐磨等性能均有显著提高。建议在机场道面工程中大力推广应用掺加引气减水剂的高性能混凝土。
In view of the common pavement concrete construction is not easy to control the workability, the strength of the reserve is low, poor durability and other phenomena, through the admixture of air-drying superplasticizer, preparation of high performance pavement concrete. Both indoor tests and field application results show that compared with common pavement concrete, the high performance pavement concrete with air-entraining water-reducing admixture has the advantages of convenient construction, good homogeneity, significant improvement in strength, frost resistance and wear resistance . Proposed in the airport pavement project to promote the use of air entraining agent admixture of high performance concrete.
