【摘要】 通过传统硫磺砂浆锚固剂中砂子、水泥作用的分析，对石屑、石粉分别代替锚固剂中的砂子、水泥的可行性进行了试验研究，讨论了石屑粒径、级配、掺量对锚固剂强度的影响并分析了其中内在原因更多还原

【Abstract】 In this paper,on the basis of traditional sulphur sand mortar proportioning for fixing screw spike,the influence of replacing sand and cement by stone screenings on the properties of sulphur mortar is investigated.The results show that replacing sand and cement by stone screenings with appropriate proportional grading and content in traditional sulphur mortar is feasible,and the mechanical behavior of this kind of sulphur screenings mortar is better than traditional sulphur sand mortar.更多还原
