机场自密实道面混凝土微观分析

Microanalysis of self-compacted concrete used in airport pavement

对某机场采用的掺粉煤灰的自密实道面混凝土的内部结构进行检验与分析,并与传统的未加矿物微细掺料的干硬性道面混凝土进行对比,孔结构与过渡层结构有明显的改善,从而证实了这种自密实道面混凝土比上述传统的道面混凝土具有较高的强度和耐久性,并能够具有较长的使用寿命。

This paper inspected and analyzed the interior structure of self-compacted concrete that used in airport pavement and mixed with ash,compared with the traditional stiff pavement concrete,the self-compacted concrete have obvious progress in pore structure and transition zone.It's result in self-compacted concrete have higher strength and durability compared with traditional concrete,and it will have longer serving life.
