Basalt fiber reactive powder concrete and preparation method thereof
The invention discloses basalt fiber reactive powder concrete and a preparation method thereof. The concrete is prepared from the following raw materials in parts by weight: 730 to 800 parts of cement, 240 to 290 parts of silica fume, 390 to 400 parts of quartz sand fine sand, 624 to 640 parts of quartz sand medium sand, 230 to 260 parts of quartz powder, 140 to 170 parts of water, 50 to 52 partsof a water reducing agent and 4 to 8 parts of basalt fibers. The axial compressive strength of the basalt fiber reactive powder concrete is close to that of steel fiber reactive powder concrete, and the breaking strength of the basalt fiber reactive powder concrete is greater than that of the steel fiber reactive powder concrete. According to the method disclosed by the invention, the dry materialand the basalt fibers are firstly mixed and stirred, so that the basalt fibers are promoted to be fully dispersed during stirring, the stirring time is shortened, and the strength of the basalt fiberreactive powder concrete is improved.
一种玄武岩纤维活性粉末混凝土及制备方法，玄武岩纤维活性粉末混凝土，以重量份数计，包括以下各原料：水泥730‑800份，硅灰240‑290份，石英砂细砂390‑400份，石英砂中砂624‑640份，石英粉230‑260份，水140‑170份，减水剂50‑52份，玄武岩纤维4‑8份。该玄武岩纤维活性粉末混凝土的轴心抗压强度接近钢纤维活性粉末混凝土的轴心抗压强度，抗折强度大于钢纤维活性粉末混凝土抗折强度。本发明的方法是先将干料与玄武岩纤维进行混合搅拌，有利于促进玄武岩纤维在搅拌时充分散开从而减少搅拌时间，提高了玄武岩纤维活性粉末混凝土的强度。
