Soft soil zone cement mixing pile slurry admixture
The invention belongs to the technical field of cement mixing pile slurry admixtures, and particularly relates to a soft soil zone cement mixing pile slurry admixture which comprises the following components in parts by weight: 25-30 parts of a cement base material, 40-60 parts of blast furnace slag, 15-20 parts of quick lime, 10-15 parts of gypsum, 1-5 parts of an active agent and 10-15 parts of fibers. According to the invention, the cement base material, the blast furnace slag, the quicklime, the gypsum, the active agent and the fiber are proportionally combined, the quicklime and the gypsum are used as excitants to improve the strength of the cement, the active agent polyethanolamine has a good grinding aiding effect and an early strength enhancing effect, and the fiber mesh is added into the material to improve the overall strength; and the overall crack resistance is improved.
本发明属于水泥搅拌桩浆液外加剂技术领域，尤其为一种软土地带水泥搅拌桩浆液外加剂，按重量份计，所述软土地带水泥搅拌桩浆液外加剂的配比为：水泥基料25‑30份，高炉矿渣40‑60份，生石灰15‑20份，石膏10‑15份，活性剂1‑5份，纤维10‑15份；本发明，通过水泥基料、高炉矿渣、生石灰、石膏、活性剂及纤维的配比组合，利用生石灰、石膏作为激发剂提高水泥的强度，活性剂多乙醇胺具有很好的助磨效果及早期强度增强效果，在材料内添加纤维网片可以提高整体的强度，增加整体的抗裂能力。
