Type II anhydrite composite excitation material and preparation method thereof
The invention discloses a type II anhydrite composite excitation material and a preparation method thereof, the type II anhydrite composite excitation material comprises the following raw materials in parts by weight: 150-300 parts of a high-activity mineral admixture, 80-150 parts of calcium hydroxide powder, 250-400 parts of PO42.5 cement, 150-200 parts of desulfurized building gypsum, 1-2 parts of inorganic salt, 1-2 parts of a defoaming agent, 1-2 parts of a water reducing agent and 1-2 parts of a stabilizing agent, and the inorganic salt is added into the high-activity mineral admixture, the calcium hydroxide powder, the PO42.5 cement, the desulfurized building gypsum, the defoaming agent, the water reducing agent and the stabilizing agent. 30-60 parts of inorganic salt, 3-6 parts of a defoaming agent, 5-10 parts of a water reducing agent and 3-10 parts of a stabilizer. According to the invention, a compact cryogel structure is formed through in-situ excitation of the desulfurized building gypsum on the type II anhydrite and composite excitation of the high-activity mineral admixture and the inorganic salt on the type II anhydrite, so that the strength and the water resistance of the type II anhydrite are improved. And the efflorescence of the system is inhibited through the synergistic effect of alkaline excitation and acid excitation.
本发明公开了一种II型无水石膏复合激发料及其制备方法，包括高活性矿物掺和料、氢氧化钙粉、PO42.5水泥、脱硫建筑石膏、无机盐、消泡剂、减水剂以及稳定剂，各原料按重量份计为：高活性矿物掺和料150‑300份，氢氧化钙粉80‑150份，PO42.5水泥250‑400份，脱硫建筑石膏150‑200份，无机盐30‑60份，消泡剂3‑6份，减水剂5‑10份，稳定剂3‑10份。本发明通过脱硫建筑石膏对II型无水石膏的原位激发，高活性矿物掺和料与无机盐对II型无水石膏的复合激发，形成一种致密的晶胶结构来提高II型无水石膏的强度及其耐水性。通过碱性激发与酸性激发协同作用，来抑制体系的泛霜。
