Quick-hardening foaming cement and preparation method thereof
The invention relates to rapid hardening foaming cement and a preparation method thereof. The rapid hardening foaming cement comprises the following raw materials in parts by mass: 40-60 parts of cement; 15-25 parts of fly ash; 3-7 parts of silica fume; 3-5 parts of calcium oxide; 5-10 parts of gypsum; 6-10 parts of calcium aluminate; 0.4-0.6 part of PP short fiber; 1-3 parts of a foaming agent; and 0.1-0.3 part of a foam stabilizer. The rapidly-hardened foaming cement obtained by the invention is generally hardened for about 10 minutes and can be demolded and unloaded after 20 minutes; rapid and continuous production can be basically carried out on a short-distance production line; and the production efficiency is greatly improved on the premise of not influencing the overall performance, and therefore, the operation cost is reduced; mainly due to the fact that gypsum, calcium aluminate, calcium carbonate, calcium carbonate, and calcium oxide act at the beginning, so that hardening is quickly realized.
一种快速硬化发泡水泥及其制备方法，包括如下质量份数的原料：水泥：40‑60份；粉煤灰：15‑25份；硅灰：3‑7份；氧化钙：3‑5份；石膏：5‑10份；铝酸钙：6‑10份；PP短纤维：0.4‑0.6份；发泡剂：1‑3份；稳泡剂：0.1‑0.3份。本申请得到的快速硬化发泡水泥一般是10min左右硬化，20min即可脱模下线，基本上可以在一个短距的生产线上进行快速的连续化生产，在不影响整体性能的前提之下，大大的提高了生产效率，从而降低了操作成本，主要是因为石膏，铝酸钙，氧化钙在开始即产生作用，使得快速实现硬化。
