Aluminum powder-based expansion type dry-mixed inorganic grouting material and preparation method thereof
The invention provides an aluminum powder-based expansion type dry-mixed inorganic grouting material and a preparation method thereof. Comprising the following components in parts by mass: 100 parts of a composite cementing material, 1-5 parts of a composite additive and 0.0001-0.0005 part of aluminum powder, the composite cementing material comprises the following components in parts by mass: 30-50 parts of calcium aluminate cement, 20-40 parts of low-temperature calcined regenerated micro powder, 10-30 parts of blast furnace slag micro powder and 1-10 parts of fluorgypsum, the composite admixture comprises the following components in parts by mass: 30-60 parts of a water reducing agent, 20-40 parts of an early strength agent, 1-10 parts of a retarder, 1-10 parts of a thickening agent and 10-20 parts of a tackifier. The aluminum powder-based expansion type dry-mixed inorganic grouting material has a certain expansion rate, relatively good bonding strength and adaptive compressive strength, so that the sealing property is relatively good, and the defects that a common inorganic grouting material is easy to shrink, poor in sealing property and the like are overcome.
本发明提供一种铝粉基膨胀型干混无机注浆材料及其制备方法。包括下述质量份的组分:复合胶凝材料100份、复合外加剂1~5份和铝粉0.0001~0.0005份;所述复合胶凝材料包括下述质量份的组分:铝酸钙水泥30~50份、低温煅烧的再生微粉20~40份、高炉矿渣微粉10~30份和氟石膏1~10份;所述复合外加剂包括下述质量份的组分:减水剂30~60份、早强剂20~40份、缓凝剂1~10份、增稠剂1~10份和增粘剂10~20份。本发明铝粉基膨胀型干混无机注浆材料具有一定的膨胀率、较好的粘结强度和适应的抗压强度,从而具有较好的密封性,克服了普通无机注浆材料易收缩、密封性差等缺点。
