Magnesium phosphate cement-based double-liquid grouting material and preparation method thereof
The invention relates to the technical field of building materials, in particular to a magnesium phosphate cement-based double-liquid grouting material and a preparation method thereof. The magnesiumphosphate cement-based double-liquid grouting material comprises a component A and a component B. The component A comprises 10-40 parts of magnesium oxide, 10-40 parts of slag powder, 1-5 parts of retarder and water, and the component B comprises 10-30 parts of phosphate, 20-40 parts of fly ash, 1-5 parts of a retarder and water. The magnesium phosphate cement-based double-liquid grouting materialprovided by the invention has the incomparable advantages compared with the traditional grouting material: the setting time is short and can be controlled within 2-15 minutes, the injectability is good, the calculus rate exceeds 100%, environmental protection is realized, the pH value of the slurry is nearly neutral, the early strength is high, the 3d compressive strength reaches 5.1 MPa, the 28dcompressive strength reaches 14.6 MPa, the water resistance is excellent, and the 28d water resistance coefficient exceeds 90% after modification.
本发明涉及建筑材料技术领域，具体涉及一种磷酸镁水泥基双液注浆材料及其制备方法，包括配合使用的组分A和组分B，其中组分A包括10~40份氧化镁、10~40份矿渣粉、1~5份缓凝剂和水；组分B包括10~30份磷酸盐、20~40份粉煤灰、1~5份缓凝剂和水。本发明提供的磷酸镁水泥基双液注浆材料具有传统注浆材料无可比拟的优势：凝结时间短且能在2‑15 min内可控；可注性好，结石率超过100%；生态环保，浆液pH值近中性；早期强度高，3 d抗压强度达5.1 MPa，28d强度达14.6MPa；耐水性优，经改性后28d耐水系数超过90%。
