摘 要:针对传统机场道面混凝土易开裂、耐久性不良的现象,采用在普通道面混凝土中掺加纤维、粉煤灰的技术路线,研究配制适合严寒干旱地区的新型高性能道面混凝土,并进行了抗裂、抗冻、抗渗、耐磨综合性能试验。试验结果表明:单掺粉煤灰或纤维,均能大大提高普通道面混凝土的抗裂性和耐久性,尤其是纤维、粉煤灰复合时,道面混凝土抗裂性和耐久性能进一步得到提高,是一种适合寒冷干旱地区的新型高性能道面混凝土。In view of the phenomenon that the traditional airfield pavement concrete is easily apt to crack and wreck,this paper mixes fiber or pulverized fuel ash into the common pavement concrete to heighten the performance of anti-crack and durability,meanwhile does the synthesizing experimental study of anti-crack,freeze-thaw,penetration and abrading. The experimental results suggest that the common concrete,if mixed with fiber or pulverized fuel ash,can heighten the performance of anti-crack and durability,especially when mixed both fiber and pulverized fuel ash at the same time,thus greatly heighten the performance of anti-crack and durability. It is the new type of high performance pavement concrete which is adapt to cold and droughty area.
