| titleOfInvention | Anti-crack concrete and preparation method thereof |
| abstract | The application relates to the field of concrete, and particularly discloses anti-crack concrete and a preparation method thereof. The anti-cracking concrete is prepared from cement, fly ash, coarse aggregate, fine aggregate, a water reducing agent, nano boron fiber, cellulose fiber, nano ammonium bicarbonate, a polyethylene glycol aqueous solution, a silane coupling agent and water; the preparation method comprises the following steps: preparing pre-modified cellulose fibers; uniformly mixing the pre-modified cellulose fiber, the nano boron fiber and the nano ammonium bicarbonate, and performing ball milling modification to obtain modified fiber; mixing cement and fly ash to prepare a cementing material; mixing the coarse aggregate, the fine aggregate and the modified fiber to prepare aggregate; mixing a water reducing agent with water to prepare a water reducing agent solution; and uniformly mixing the cementing material, the aggregate and the water reducing agent solution to obtain the anti-crack concrete. The anti-cracking concrete can be used as a building material and has the advantage of good anti-cracking performance. |
