Chemical corrosion resistant aluminoferrite cement concrete and preparation method thereof
The invention relates to the technical field of building materials, and discloses chemical-corrosion-resistant aluminoferrite cement concrete and a preparation method thereof.The molecular structure of sodium alginate is rich in carboxyl, sodium alginate can generate coordination crosslinking with Ca < 2 + > and Al < 3 + > in blast furnace slag to form hydrogel of a three-dimensional structure, the hydrogel and an original covalent network form a compact dual-network structure, and the chemical-corrosion-resistant aluminoferrite cement concrete is prepared. External ions are not easy to diffuse, and the corrosion resistance of the concrete is enhanced; the organic silicon fluorine epoxy modified acrylic emulsion can form a waterproof layer on the surface of the concrete to prevent erosion factors from entering in a physical barrier manner, so that the corrosion resistance of the concrete is further improved; the cross-linking density of the whole mixed network is also increased through interpenetration and interpenetration of the organic hydrogel and the inorganic filler, the mechanical strength and the anti-permeability performance of the concrete material are further improved through inner doping and outer coating processes, and the concrete material is low in cost, environmentally friendly and easy to industrially produce.
本发明涉及建筑材料技术领域,且公开了一种抗化学腐蚀铁铝酸盐水泥混凝土及其制备方法,海藻酸钠的分子结构中富含羧基,可以和高炉矿渣中的Ca2+、Al3+产生配位交联形成具有三维结构的水凝胶,与原有的共价网络构成致密的“双重网络”结构,使得外部离子不易扩散,增强混凝土的耐腐蚀性能;有机硅氟环氧改性丙烯酸乳液可以在混凝土表面形成防水层,以物理阻隔的方式阻止侵蚀因子的进入,进一步提高了混凝土的抗腐蚀性能;有机水凝胶和无机填料的相互渗透、穿插也增加了整个混合网络的交联密度,通过“内掺”和“外涂”工艺,进一步提高了混凝土材料的力学强度和抗渗性能,成本低廉、环保,易于工业化生产。
