石屑硫磺道钉锚固剂的研究

Investigation of Stone-grains Sulphur Mortar Anchoring Solvent

以传统的硫磺砂浆道钉锚固剂配合比为基础，利用石屑代替配料中的砂子。通过改变石屑掺量和石屑粒径的分布．研究对道钉锚固剂各项性能尤其是对抗拉强度、抗压强度、抗拔力的影响。结果表明，采用粒经和掺量合适的石屑来代替传统硫磺砂浆中的砂子，是完全可行的，且其性能优于传统硫磺砂浆的性能。

The pcr formance of a kind of ancboring solvcnt is studied in wbich sand is replaced by stone-grains. The result shows that tht perrormance of the anchoring solvent with stone-grains sulphur mortar is better than tbat of anchoring solvent with traditional sulphur mortar.
