Early high-strength sprayed concrete slurry, early high-strength shotcrete and construction method thereof
Early high-strength sprayed concrete slurry relates to the technical field of constructional engineering materials, and comprises cement, an early high-strength admixture, sand, gravels, a water reducing agent and water. The early high-strength sprayed concrete slurry is scientific and reasonable in formula and simple and easily available in raw materials, and can effectively improve the early strength of concrete and can achieve a better supporting effect on the premise of maintaining the early-strength sprayed concrete slurry conveying performance and meeting a wet spraying process through the specially-made early-strength admixture. The embodiment of the invention further provides early-strength and high-strength sprayed concrete and a construction method thereof, the construction method adopts the early-strength and high-strength sprayed concrete slurry and an accelerator for mixing and wet spraying, and high-strength concrete is obtained in a short time through the activation effect of the accelerator.
一种早高强喷射混凝土浆体，涉及建筑工程材料技术领域，其包括水泥、早高强掺合料、砂、碎石、减水剂、以及水。其配方科学合理，原料简单易得，通过特制的早高强掺合料，可以做到在保持早高强喷射混凝土浆体输送性能，满足湿喷工艺的前提下，有效提高混凝土的早期强度，达到更好的支护效果。本发明实施例还提供了一种早高强喷射混凝土及其施工方法，该施工方法采用上述早高强喷射混凝土浆体与速凝剂混合湿喷，通过速凝剂的激活作用，在短时间内获得高强度的混凝土。
