Quick-setting filling cementing material
The invention discloses a quick-setting filling cementing material and a preparation method thereof. The composition comprises the following components in parts by weight: 40-90 parts of slag powder;6-24 parts of cement clinker; 2-18 parts of bentonite, 2-28 parts of steel slag powder; 0-15 parts of modified gypsum; 0.5-10 parts of an alkaline excitant; 0-10 parts of a coagulant; 1-3 parts of a water reducing agent; 0.2-8 parts of an anti-cracking material; and 0.5-10 parts of a suspension agent. The quick-setting filling cementing material can effectively reduce the dosage of an additive, has good flowing property and relatively high early strength, has good retention strength and volume stability, is short in cementing time, quick in early strength increase and slow in later strength increase, and is simple in process and wide in material source.
本发明公开了本发明提供一种快凝充填胶凝材料，组成按重量份分别为：矿渣粉40‑90份，水泥熟料6‑24份，膨润土2‑18份，钢渣粉2‑28份，改性石膏0‑15份，碱性激发剂0.5‑10份，促凝剂0‑10份，减水剂1‑3份，抗裂材料0.2‑8份，悬浮剂0.5‑10份，该快凝充填胶凝材料可以有效降低添加剂用量、具备良好的流动性能和较高的早期强度，具有良好的保持强度和体积稳定性，胶凝时间短，早期强度增长快，后期强度缓慢增长，工艺简单，材料来源广泛。
