Anti-cracking impervious concrete
The invention provides anti-crack impervious concrete, belonging to the technical field of building materials. The anti-crack impervious concrete comprises the following components in parts by mass: 200 to 300 parts of cement, 100 to 150 parts of coal ash, 950 to 1100 parts of gravels, 850 to 1050 parts of sand, 0.5 to 1 part of nanometer inorganic oxide, 0.5 to 1 part of nanometer zinc oxide, 6 to 12 parts of an additive, 1 to 3 parts of a self-repairing agent and 155 to 170 parts of water. According to the invention, the nanometer inorganic oxide, the nanometer zinc oxide, the additive and the self-repairing agent are used as main raw materials, the small-size effect, the surface interface effect, the self-repairing effect, the surface energy condition technology and the like of nanomaterials are used for improving and optimizing the pores and compactness of the concrete, and water is blocked through self-repairing to repair cracks; a hydration heat release rate and pore solution surface energy are reduced by inhibiting moisture evaporation of a concrete mixture in condensation and hardening, so the volume stability of the concrete is maximized; and finally, self-repairing is conducted on cracks which possibly occur. Therefore, the concrete has crack resistance and impermeability in a full-period range, and the durability and the structural safety of the concrete are improved.
本发明提供一种抗裂防渗混凝土，属于建筑材料技术领域。包括以下质量份的各组分：水泥200～300份、粉煤灰100～150份、碎石950～1100份、砂850～1050份、纳米无机氧化物0.5～1份、纳米氧化锌0.5～1份、外加剂6～12份、自修复剂1～3份，水155～170份。本发明以纳米无机氧化物、纳米氧化锌、外加剂、自修复剂为主要原料，利用纳米材料的小尺寸效应、表面界面效应、自修复效应以及表面能条件技术等改善优化混凝土孔隙和密实度，自修复阻断水分修复裂缝；通过抑制混凝土拌合物凝结硬化水分蒸发，降低水化放热速率与孔溶液表面能，从而实现混凝土体积稳定性最大化；最后将可能出现的裂缝进行自修复；进而实现在混凝土全周期范围内均具有抗裂性和抗渗性，改善混凝土耐久性和结构安全。
