采取以下技术措施， 研制出高性能喷射混凝土： （１） 研制高活性细掺料， 提高胶凝材料的强度和粘聚性； （２） 确定粗细骨料最佳配比， 提高骨料强度； （３） 提高胶凝材料与骨料界面的强度； （４） 降低用水量， 并实施养护． 工业性试验结果表明， 回弹率降到１０ ％ 以下， 粉尘降到２０ ｍｇ／ｍ３ 以下， 喷射混凝土强度达到３５－６ ＭＰａ ， 巷道总成本降低２０ ％ ．
Take the following technical measures to develop high-performance shotcrete: (1) Develop high-activity fine admixtures to improve the strength and cohesiveness of the cementitious materials; (2) Determine the best ratio of coarse and fine aggregates and increase the aggregate strength; (3) Improve the strength of the interface between cementitious materials and aggregates; (4) Reduce water consumption and implement conservation. Industrial test results show that the rebound rate drops below 10%, the dust drops below 20 mg/m3, the shotcrete strength reaches 35-6 MPa, and the total cost of the roadway decreases by 20%.
