【摘要】：針對(duì)噴射混凝土的施工特點(diǎn)和預(yù)拌干料的特性,對(duì)預(yù)拌噴射混凝土干料的配合比進(jìn)行試驗(yàn)研究,結(jié)果表明在預(yù)拌噴射混凝土干料中摻入高性能復(fù)合外加劑,可顯著提高噴射混凝土的性能,適用于明挖護(hù)坡、地下暗挖工程噴錨及橋梁、柱墩等的修復(fù)和加固。
[Abstract]:In view of the construction characteristics of shotcrete and the characteristics of premixed dry materials, the mixture ratio of premixed shotcrete dry materials is studied experimentally. The results show that high performance composite admixture is added to the dry mix of shotcrete dry materials. It can significantly improve the performance of shotcrete, and can be used to repair and reinforce Yu Ming excavation slope protection, shotcrete anchor and bridge, column piers, etc.
