Rapid curing agent for cast-in-place pile foundation slurry as well as preparation method and application of rapid curing agent
The invention discloses a cast-in-place pile foundation slurry rapid curing agent and a preparation method and application thereof, and relates to the field of curing treatment, the cast-in-place pile foundation slurry rapid curing agent comprises the following components by weight: 20-60 parts of granulated blast furnace slag, 20-60 parts of calcined coal gangue, and 20 parts of an alkali activator, the alkali activator is water glass, and the modulus of the water glass is 1.0-1.3. The preparation method comprises the following steps: preparing calcined coal gangue; preparing water glass; and mixing and stirring the granulated blast-furnace slag and the calcined coal gangue to obtain the rapid curing agent. The application comprises the following steps: air-drying slurry to prepare sludge; adding a rapid curing agent into the sludge, mixing and uniformly stirring; and filling into a test mold, compacting, standing, removing the mold, curing, and checking after curing to a to-be-detected age. According to the present invention, the design is reasonable, the curing agent has characteristics of good curing effect and rapid reaction on the treatment of the cast-in-place pile foundation slurry, the mechanical property is met, and the economic cost is reduced.
本发明公开了一种灌注桩基础泥浆快速固化剂及其制备方法与应用，涉及固化处理领域，包括以下重量份数的组分：粒化高炉矿渣20~60份、煅烧煤矸石20~60份、碱激发剂20份，所述碱激发剂为水玻璃，所述水玻璃的模数为1.0~1.3。其制备方法包括以下步骤：制备煅烧煤矸石；制备水玻璃；混合搅拌粒化高炉矿渣和煅烧煤矸石，得到快速固化剂。应用包括以下步骤：泥浆风干配制为淤泥；向淤泥中加入快速固化剂混合并搅拌均匀；填充入试模中压实，静置后拆模养护，养护至待测龄期检验。本发明设计合理，此种固化剂在灌注桩基础泥浆的处理上，不仅固化效果良好，而且反应快速，还满足力学性能降低了经济成本。
