摘要
着重研究了如何利用正交实验模拟现场岩石的物理力学性能 ;水灰比、水泥用量对水泥砂浆强度的影响 ;水泥砂浆 7天与 2 8天强度的关系 ;
This paper gives experimentations and researchs on how to simulate the physical and mechanical properties of the rock's on the site with orthogonal test .the effects of water-cement ratio and consumption of cement relate to the strength of cement mortar; the relations of cement mortar between the seven day's strenth and the twenty-eight day's strenth; In the end ,author found a good mixture ratio of cement-gypsum composite mortar which properties similar to the rock's in the site .
