Tunnel jet type high-ductility concrete material and preparation method thereof
The invention discloses a tunnel jet type high-ductility concrete material and a preparation method thereof. The jet type high-ductility concrete material is prepared from the following raw materials in parts by mass: 1 part of a cementing material, 1.03 parts of machine-made sand, 0.04 part of an expanding agent, 0.74 part of water, 0.016 part of a water reducing agent, 0.015 part of a shrinkage reducing agent, 0.069 part of an accelerator, 0.03 part of PVA fibers and 0.021 part of PP fibers. The shotcrete has the advantages of excellent ductility, impact resistance, low shrinkage, permeability resistance and the like, meanwhile, the construction performance is good, and various performance requirements of tunnel engineering on shotcrete under complex conditions are completely met.
本发明公开了一种隧道喷射型高延性混凝土材料及其制备方法，该喷射型高延性混凝土材料由以下质量份数的原料制成：胶凝材料1份、机制砂1.03份、膨胀剂0.04份、水0.74份、减水剂0.016份、减缩剂0.015份、速凝剂0.069份、PVA纤维0.03份、PP纤维0.021份。有益效果：本发明具备优异的延性、抗冲击、低收缩、抗渗等优点，同时施工性能良好，完全满足复杂条件下隧道工程对于喷射混凝土的各项性能要求。
