【摘要】:针对喷射混凝土的施工特点和预拌干料的特性,对预拌喷射混凝土干料的配合比进行试验研究,结果表明在预拌喷射混凝土干料中掺入高性能复合外加剂,可显著提高喷射混凝土的性能,适用于明挖护坡、地下暗挖工程喷锚及桥梁、柱墩等的修复和加固。
[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.
