Slag-modified desulfurized gypsum-based mud curing material and preparation method thereof
The invention provides a slag-modified desulfurized gypsum-based mud curing material and a preparation method thereof. The slag-modified desulfurized gypsum-based mud curing material is prepared from the following raw material components in parts by weight: 60 to 70 parts of granulated blast furnace slag powder, 1 to 5 parts of modified desulfurized gypsum, 1 to 35 parts of an activity enhancing component and 0.01 to 5 parts of an activity exciting agent, the modified desulfurized gypsum comprises alpha-semi-hydrated gypsum, beta-semi-hydrated gypsum and dihydrate gypsum, wherein the content of the semi-hydrated gypsum is greater than or equal to 70%. The slag-modified desulfurized gypsum-based mud curing material provided by the invention realizes industrial solid waste recycling, low cost and simple process, and can solve the problems of difficult pumping, large bleeding amount, long hardening and setting time and the like of the conventional flow-state solidified soil freshly-mixed mud when being applied to preparation of flow-state solidified soil while being applied to preparation of the flow-state solidified soil; and the construction performance and the later mechanical property of the flow-state solidified soil are optimized.
本发明提供了一种矿渣‑改性脱硫石膏基泥浆固化材料及其制备方法，所述矿渣‑改性脱硫石膏基泥浆固化材料包括按重量份数计的如下原料组分：粒化高炉矿渣粉60～70份、改性脱硫石膏1～5份、活性增强组分1～35份、活性激发剂0.01～5份；所述改性脱硫石膏包括α‑半水石膏、β‑半水石膏和二水石膏，其中半水石膏含量≥70％。本发明所述的矿渣‑改性脱硫石膏基泥浆固化材料在实现工业固废再利用、成本低廉、工艺简单的同时，应用到制备流态固化土中时，可解决常规流态固化土新拌泥浆存在的泵送难、泌水量大、硬化凝结时间长等问题，优化了流态固化土的施工性能及后期力学性能。
