The invention provides anti-crack concrete, and relates to the field of concrete preparation. The anti-crack concrete comprises the following components in parts by weight: 25-38 parts of cement, 15-25 parts of water, 30-60 parts of coarse aggregate, 15-30 parts of fine aggregate, 3-8 parts of a viscous material, 3-5 parts of fibers, 1-2 parts of a water reducing agent, 1-1.5 parts of a modifier, 1-2 parts of nanoparticles, 5-9 parts of cement particles and 2-3 parts of a fiber reinforcing agent. A proper amount of nano-particles and cement particles are added inside, a gel body is formed after a hydration reaction, aggregate in concrete can be firmly bonded, so that the strength required by the concrete is provided, meanwhile, pores in the concrete can be filled, the porosity of the concrete is reduced, and the compactness and impermeability of the concrete are improved; meanwhile, the specific viscous material, the coarse aggregate, the modifier and the fiber reinforcing agent are added, so that the tensile strength and the crack resistance of the concrete are improved, the cracking tendency of the concrete is effectively reduced, the service life of the structure is prolonged, and the maintenance cost is reduced.
本发明提供一种抗裂混凝土，涉及混凝土制备领域。该抗裂混凝土，包括以下重量份数的组分：水泥25‑38份、水15‑25份、粗骨料30‑60份、细骨料15‑30份、黏性材料3‑8份、纤维3‑5份、减水剂1‑2份、改性剂1‑1.5份、纳米颗粒1‑2份、水泥颗粒5‑9份和纤维增强剂2‑3份。通过在内部添加适量的纳米颗粒和水泥颗粒，经过水化反应后形成胶凝体，能够牢固地粘结混凝土中的骨料，从而提供混凝土中所需的强度，同时还能够填充混凝土中的孔隙，减少混凝土的孔隙率，提高混凝土的密实性和抗渗性，从而提高混凝土的耐久性，同时添加特定的黏性材料、粗骨料、改性剂和纤维增强剂，改善混凝土的抗拉强度和抗裂性能，有效减少混凝土的开裂倾向，延长结构的使用寿命和减少维护成本。
