Environment-friendly shotcrete slurry, environment-friendly shotcrete and construction method of environment-friendly shotcrete
The embodiment of the invention provides an environment-friendly shotcrete slurry, and relates to the technical field of constructional engineering materials. The environment-friendly shotcrete slurry comprises cement, a low-cost admixture, sand, broken stone, a water reducing agent and water. According to the present invention, the formula is scientific and reasonable, the raw materials are simple and easily available, and with the elaborately-prepared low-cost admixture, the cement consumption can be effectively reduced on the premise of maintaining the conveying performance and the strength performance of the environment-friendly sprayed concrete slurry so as to achieve the effects of low cost and environmental protection. The embodiment of the invention also provides environment-friendly sprayed concrete and a construction method thereof, the construction method adopts the environment-friendly sprayed concrete slurry and accelerator mixed wet spraying, the operation is simple and convenient, and the obtained environment-friendly sprayed concrete still maintains better performance under the condition of reducing the cement consumption.
本发明实施例提供了一种环保型喷射混凝土浆体，涉及建筑工程材料技术领域，其包括水泥、低成本掺合料、砂、碎石、减水剂、以及水。其配方科学合理，原料简单易得，通过精心配置的低成本掺合料，可以在保持环保型喷射混凝土浆体的输送性能、强度性能的前提下，有效减少水泥用量，达到低成本、绿色环保的效果。本发明实施例还提供了一种环保型喷射混凝土及其施工方法，该施工方法采用上述环保型喷射混凝土浆体与速凝剂混合湿喷，其不仅操作简单方便，而且得到的环保型喷射混凝土在降低了水泥用量的情况下，依旧保持有较佳的性能。
