Test and Application of Sulpho-aluminate Cement Quick Setting Slurry in Anchor Cable Boring for Wall Consolidation

Abstract:

To solve the difficulties of borehole completion in high slope anchor cable drilling construction for Futang hydropower plant, by the laboratory experimental study, the quick setting slurry with sulpho-aluminate cement as main agent adding special early strength agent and retarder was taken, which greatly shortened the hole cleaning and stay setting time after grouting for wall consolidation, improved the construction efficiency of anchor cable boring. The paper introduced the testing process, testing results, engineering application and the effects in detail.
