Mineral admixture ternary cementing material and preparation method thereof
The invention discloses a mineral admixture ternary cementing system and a preparation method thereof. The preparation method comprises the following steps: placing a raw material SAP in a NaCl solution, and soaking for 1-2 days to obtain water-swelling SAP; weighing lithium acetate, sodium acetate, sodium caprylate, sodium hydroxide and calcium hydroxide according to a certain ratio, placing at 300-350 DEG C, carrying out heat preservation for 20-40 minutes, cooling, and grinding to obtain slow-release glass; weighing mineral powder, fly ash, the slow-release glass and the water-swelling SAPaccording to a certain mass ratio, mixing, and uniformly stirring to obtain a ternary cementing material; pouring the ternary cementing material into a mold, curing, and demolding to obtain the finalproduct. The cementing system can be used in water-deficient areas, and is short in preparation period and good in repeatability.
本发明公开了一种矿物掺合料三元胶凝体系及其制备方法，制备方法包括以下步骤：将原料SAP置于NaCl溶液中，浸泡1‑2天，获得吸水膨胀的SAP；按照配比称取乙酸锂：乙酸钠：辛酸钠：氢氧化钠：氢氧化钙，置于300‑350℃，保温20‑40分钟，冷却后研磨制得缓释玻璃；按质量比称取矿粉和粉煤灰、缓释玻璃、吸水膨胀的SAP，混合，搅拌至均匀，得三元胶凝材料；将三元胶凝材料倒入模具，养护、脱模后得到最终产品；该胶凝体系能够满足缺水地区使用，制备周期短、重复性好。
