Phosphogypsum-based grouting material as well as preparation method and application thereof
The invention discloses a phosphogypsum-based grouting material as well as a preparation method and application thereof. The concrete comprises the following raw materials in parts by mass: 10-30 parts of water, 20-30 parts of cement, 20-30 parts of fly ash, 45-55 parts of lime, 40-60 parts of phosphogypsum, 35-45 parts of sand, 0-18 parts of steel fiber, 5-25 parts of limestone, 0.05-0.4 part of a water reducing agent and 0.02-0.4 part of an early strength agent. The prepared grouting material is high in fluidity and high in strength, can be used for grouting detection, realizes a non-drilling test through resistivity, and is beneficial to engineering integrity.
本发明公开一种磷石膏基灌浆材料及其制备方法和应用。按质量份数计，包括以下原料：水10‑30份，水泥20‑30份，粉煤灰20‑30份，石灰45‑55份，磷石膏40‑60份，砂35‑45份，钢纤维0‑18份，石灰石5‑25份，减水剂0.05‑0.4份，早强剂0.02‑0.4。本发明制备的灌浆材料流动性好、强度高，且可用于灌浆检测，通过电阻率实现非钻入测试，有利于工程完整性。
