Anti-cracking special fiber concrete and preparation method thereof
The invention relates to the field of fiber concrete, and particularly discloses anti-cracking special fiber concrete and a preparation method thereof. The anti-cracking special fiber concrete is prepared from the following raw materials in parts by weight: 5 to 10 parts of anti-cracking special fiber, 35 to 45 parts of gravel, 50 to 70 parts of sand, 40 to 60 parts of cement, 15 to 35 parts of a cementing material, 1.0 to 1.5 parts of an additive, 0.2 to 0.5 part of water-absorbent resin and 50 to 70 parts of water, the anti-cracking special fiber is prepared from 2 to 4 parts of PVA (Polyvinyl Alcohol) fiber, 2.8 to 5.5 parts of carbon fiber and 0.2 to 0.5 part of coupling agent; the parts by weight are all based on the anti-cracking special fibers. The anti-cracking special fiber concrete disclosed by the invention has the effects of excellent anti-cracking performance and lasting anti-cracking performance.
本申请涉及纤维混凝土领域，具体公开了一种防裂特种纤维混凝土及其制备方法。本申请的防裂特种纤维混凝土由以下重量份的原料制得：防裂特种纤维5~10份，碎石35~45份，砂50~70份，水泥40~60份，胶凝材料15~35份，外加剂1.0~1.5份，吸水树脂0.2~0.5份，水50~70份；所述防裂特种纤维由2~4份PVA纤维，2.8~5.5份碳纤维与0.2~0.5份偶联剂制备得到；上述重量份均以防裂特种纤维为基准。本申请的防裂特种纤维混凝土具有抗裂性能优异与抗裂性能持久的效果。
