Concrete crack self-repairing agent suitable for marine corrosion conditions
The invention discloses a concrete crack self-repairing agent suitable for marine corrosion conditions. The concrete crack self-repairing agent comprises a component I and a component II, the component I and the component II are of core-shell structures; the outer shell of the component I is a polymer film; the inner layer comprises the following components in percentage by mass: 20-30% of barite powder, 50-60% of a magnesium source and 20-30% of cement; the outer shell of the component II is a polymer film; the inner layer comprises the following components in percentage by mass: 20-30% of barite powder, 5-10% of microbial powder, 20-30% of glucose, 20-40% of an aluminum source and 10-30% of low-alkali cement. The repairing agent disclosed by the invention is continuously-graded solid granular small balls and replaces concrete fine aggregate with equal mass. Through the synergistic effect of microorganism mineralization and metal mineral hydration, concrete crack space filling and crack invasion corrosion ion curing are achieved, and the corrosion inhibitor is especially suitable for the marine corrosion environment.
本发明公开了一种适用于海洋腐蚀条件的混凝土裂缝自修复剂，包括组分一和组分二；所述组分一、组分二均为核壳结构；所述组分一的外层壳体为聚合物薄膜；内层按质量百分比包括以下组分：重晶石粉20％‑30％，镁源50％‑60％，水泥20％‑30％；所述组分二的外层壳体为聚合物薄膜；内层按质量百分比包括以下组分：重晶石粉20‑30％，微生物粉末5‑10％，葡萄糖20‑30％，铝源20％‑40％，低碱水泥10％‑30％。本发明的修复剂为连续级配实心颗粒小球，等质量替代混凝土细骨料。通过微生物矿化与金属矿物水化协同作用，实现混凝土裂缝空间的填充和入侵裂缝腐蚀离子的固化，尤其适用于海洋腐蚀环境。
