Anti-crack anti-seepage self-repairing C35 mass concrete
The invention relates to anti-cracking anti-seepage self-repairing C35 mass concrete. The mass concrete is prepared from the following ingredients in parts by mass: 200 to 290 parts of cement, 0 to 50 parts of mineral powder, 30 to 100 parts of coal ash, 0.1 to 0.3 part of an air entraining agent, 700 to 850 parts of fine aggregate, 1000 to 1100 parts of coarse aggregate, 155 to 175 parts of water, 4 to 10 parts of a retarding type water reducing agent, 25 to 35 parts of an anti-cracking agent and 5 to 10 parts of silicone-modified SAP particles. The C35 mass concrete has the beneficial effects that the C35 mass concrete has continuous micro-expansibility and internal curing performance on the basis of having conventional performance such as workability, mechanical property, impermeability and freeze-thaw resistance of concrete, and has the crack self-repairing performance and the function of preventing continuous expansion of cracks while improving the anti-cracking and anti-seepage performance of the concrete.
本发明涉及抗裂防渗自修复C35大体积混凝土，包括如下质量份数的组分：水泥200‑290份、矿粉0‑50份、粉煤灰30‑100份、引气剂0.1‑0.3份、细骨料700‑850份、粗骨料1000‑1100份、水155‑175份、缓凝型减水剂4‑10份、抗裂剂25‑35份、硅酮改性SAP颗粒5‑10份。本发明的有益效果为：C35大体积混凝土在满足混凝土和易性、力学性能、抗渗性和抗冻融性等常规性能的基础上具有持续微膨胀性和内养护性能，提高混凝土抗裂防渗性能的同时，具有裂缝自修复性能，预防裂缝持续扩展的功能。
