Alkali-activated sodium jarosite slag cement composite material and preparation method thereof
The invention relates to the technical field of cement materials, in particular to an alkali-activated sodium jarosite slag cement composite material and a preparation method thereof. The raw materials of the alkali-activated sodium jarosite slag cement composite material comprise the following components in parts by weight: 850-950 parts of sodium jarosite slag; 0-95 parts of cement; 0 to 209 parts of water; 170-418 parts of an alkaline activator, wherein the alkaline activator contains at least 50% by mass of alkaline papermaking waste liquid, wherein the mass ratio of the cement to the sodium jarosite slag is 0 to 0.1; the ratio of the total weight of the water and the alkaline activator to the total weight of the sodium jarosite slag and the cement is 0.2-0.5. The alkali-activated sodium jarosite slag cement composite material effectively solves the problems of stockpiling and difficult treatment of sodium jarosite slag, the preparation cost of a traditional alkali-activated cementing material can be reduced to a certain extent, waste utilization, environmental protection and resource saving are realized, and a formed cement test block has relatively good mechanical strength performance, so the alkali-activated sodium jarosite slag cement composite material has a very good application prospect.
本申请涉及水泥材料技术领域，尤其涉及一种碱激发黄钠铁矾渣水泥复合材料及其制备方法。碱激发黄钠铁矾渣水泥复合材料的原料包括如下重量份的组分：黄钠铁矾渣850‑950份；水泥0‑95份；水0‑209份；碱性激发剂170‑418份，碱性激发剂中含有至少50％质量分数的碱性造纸废液；其中，水泥与黄钠铁矾渣的质量比为0‑0.1；水和碱性激发剂的总重量与黄钠铁矾渣和水泥的总重量的比例为0.2‑0.5。该碱激发黄钠铁矾渣水泥复合材料有效解决黄钠铁矾渣堆存、难处理问题，可一定程度降低传统碱激发胶凝材料的制备成本，实现利废环保、节约资源，而且形成的水泥试块具有较好的力学强度性能，因此，具有很好的应用前景。
