Long-life concrete and preparation method thereof
The invention relates to the field of building materials, in particular to long-life concrete and a preparation method thereof. Raw materials of the long-life concrete comprise a gel material, sand, gravel, water and an additive, the gel material is composed of cement, slag powder, fly ash and silica fume, the mass of the sand accounts for 30-32% of the total mass of the sand and the gravel, and the mass ratio of the gel material to the sand to the water in per cubic meter of the concrete is 550-560: 500-540: 160-165. By adjusting the raw material compatibility of the concrete, the probability that the concrete cracks and the crack width after cracking are reduced, the penetration resistance and crack resistance of the concrete are improved, and the service life is prolonged. Furthermore, after the self-repairing capsule is added, the crack can be quickly responded and bonded, passivated or prevented from developing, so that the appearance is kept intact, the performance of the material is recovered, and the application scene is rich.
本发明涉及建筑材料领域，尤其涉及一种高寿命混凝土及其制备方法。所述高寿命混凝土其原料包括凝胶材料、砂、碎石、水和外加剂，所述凝胶材料由水泥、矿渣粉、粉煤灰和硅灰组成，所述砂的质量占砂和碎石总质量的30‑32％，单方混凝土中凝胶材料、砂和水的质量比为550‑560：500‑540：160‑165。本发明通过调整混凝土的原料配伍，从而降低混凝土出现裂缝的概率和开裂后的裂缝宽度，提高混凝土的抗渗透性能和抗裂性，延长服役寿命。进一步地，加入自修复胶囊后，能够快速响应并粘接裂缝，钝化或阻止裂缝的发展，从而保持外观完好并恢复材料性能，应用场景丰富。
