摘　　要：随着高速铁路的飞速发展,板式无碴轨道应用日益广泛。CA砂浆在板式无碴轨道中起到减缓震动的作用,是板式无碴轨道的关键组成部分。在国内外高速铁路建设中,CA砂浆已经被广泛应用。总结分析了当前国内CA砂浆的基本性能研究、耐久性及CA砂浆与板式轨道动力学性能研究的现状,并在此基础上对今后CA砂浆的研究方向做出展望。With the rapid development of high-speed railway, slab track is applied widely. CA mortar play the role of reducing-vibration in the slab track, and it is a key component of the slab track. With the high-speed railway construction, CA mortar has been large-scale used. The domestic research of the basic properties, the durability and the CA mortar and slab track＇s dynamic performance of CA mortar are summarized and analyzed. Accordingly, a prospect of CA mortar＇s future research is put forward.
