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。
In this paper, the mix proportion of the dry-mixture materials for shotcrete was studied according to the construction characteristics and its performance. The results showed that, high performance composite additives can significantly improve the performance of the dry-mixture materials for shotcrete, it was suitable for repairing and strengthening the construction of the structure of the excavated slope protection project, the underground spray anchor, the bridge, the pier and the like.
