Green high-performance mineral admixture for concrete and preparation method of green high-performance mineral admixture
The invention provides a green high-performance mineral admixture for concrete and a preparation method, and belongs to the technical field of building materials. The superfine converter slag and the silica fume are used in cooperation, under the condition that sodium hydroxide, liquid sodium silicate and sodium chloride serve as alkali excitants, formation of a hydration product calcium silicate is promoted, and therefore the gel material is formed, meanwhile, the PE fibers are used in cooperation, and therefore the anti-permeability of the gel material is improved, and the service life of the gel material is prolonged. And the hydroxypropyl methyl cellulose is added into the formula, so that the dissolving-out amount of heavy metals of the obtained green high-performance mineral admixture during use of the concrete is also ensured.
本发明提供了一种用于混凝土的绿色高性能矿物掺合料及制备方法，属于建筑材料技术领域。本发明通过将超细转炉渣和硅灰配合使用，在氢氧化钠、液体水玻璃和氯化钠作为碱激发剂的情况下，促进水化产物硅酸钙的形成，从而形成胶凝材料，同时配合PE纤维的使用，从而提高凝胶材料的抗渗性，并且通过在配方中加入羟丙基甲基纤维素，还保证了获得的绿色高性能矿物掺合料在混凝土使用时的重金属的溶出量。
