Environment-friendly high-strength composite Portland cement material and preparation method thereof
The invention discloses an environment-friendly high-strength composite Portland cement material and a preparation method thereof. The raw materials comprise 500-600 parts of Portland cement, 200-240 parts of fly ash and 125-150 parts of household garbage incineration fly ash subjected to water washing pretreatment; oscillating a mixed solution obtained by mixing the fly ash and the tap water, performing solid-liquid separation on the mixed solution after oscillation, and filtering and taking out a solid; repeating the steps, drying the filtered solid to obtain caked fly ash, and performing physical grinding on the caked fly ash to obtain fly ash subjected to water washing pretreatment; and uniformly mixing and stirring the fly ash subjected to washing pretreatment, the fly ash and the Portland cement to obtain a product. The green and environment-friendly high-strength composite Portland cement is prepared through the performance complementation and synergistic effect of the two admixtures, has high early and later strength, and meanwhile can achieve resource utilization of waste to the maximum extent, reduce environmental pollution, save natural resources and relieve the pressure of resource shortage.
本发明公开了一种环保的高强型复合硅酸盐水泥材料及制备方法。原料包括硅酸盐水泥500‑600份，粉煤灰200‑240份，水洗预处理的生活垃圾焚烧飞灰125‑150份；将飞灰与自来水混合后的混合溶液振荡，振荡后对混合溶液固液分离，将固体过滤取出；重复以上步骤，后将过滤后的固体烘干，后获得结块飞灰，将结块飞灰通过物理研磨方法制得水洗预处理的飞灰；取水洗预处理的飞灰、粉煤灰和硅酸盐水泥混合搅拌均匀即得产物。本发明通过两种掺合料的性能互补及协同作用，制备出绿色环保的高强型复合硅酸盐水泥，具有较高的早期和后期强度，同时可以最大限度地实现废弃物的资源化利用，减少环境污染，节约自然资源，缓解资源短缺压力。
