Concrete self-healing crystallization protection material as well as preparation method and application thereof
The invention relates to the technical field of building materials, in particular to a concrete self-healing crystallization protection material and a preparation method thereof. The material is prepared from the following components in parts by mass: 20 to 30 parts of nano silica sol, 10 to 15 parts of super absorbent polymer, 10 to 20 parts of penetrant, 30 to 50 parts of solid waste, 10 to 15 parts of solid activator and 5 to 10 parts of metal oxide, wherein the solid waste consists of slag, fly ash and silica fume in a mass ratio of (10-20): (8-10): (15-20); the solid exciting agent consists of sludge, red mud and plant ash in a mass ratio of (5-10): (8-10): (10-15); the metal oxide is composed of magnesium oxide and aluminum oxide in a mass ratio of (1-1.5): (1-2). The self-healing crystallization protection material has good permeability, and can fully fill capillary micropores and fine cracks of concrete to realize repair of the concrete cracks.
本发明涉及建筑材料技术领域，具体涉及一种混凝土自愈合结晶防护材料及其制备方法。该材料包括以下质量份数的组分：纳米硅溶胶20‑30份、高吸水性聚合物10‑15份、渗透剂10‑20份、固体废弃物30‑50份、固体激发剂10‑15份和金属氧化物5‑10份；其中，固体废弃物由质量比为10‑20:8‑10:15‑20的矿渣、粉煤灰和硅灰组成；固体激发剂由质量比为5‑10:8‑10:10‑15的淤泥、赤泥和草木灰组成；金属氧化物由质量比为1‑1.5:1‑2氧化镁和氧化铝组成。该自愈合结晶防护材料的渗透性好，能够充分填充到混凝土的毛细微孔和细微裂缝处，实现混凝土裂缝的修复。
