Novel rapid repair cement based on magnesium oxysulfate cementing material and preparation method thereof
The invention provides novel rapid repair cement based on a magnesium oxysulfate cementing material and a preparation method thereof. The material is characterized by being prepared from the followingraw materials in parts by weight: 45 to 55 parts of light calcined magnesia powder, 30 to 40 parts of magnesium sulfate solution, 2 to 7 parts of aluminate cement clinker with the mark number of CA-50 or CA-70, and 0.2 to 0.7 part of citric acid. According to the novel rapid repair cement based on the magnesium oxysulfate cementing material, the cement has the advantages of simple preparation process, short setting time, high early strength, good stability, cost reduction and environmental protection on the premise of ensuring the use strength, impermeability, stability and other properties of the cement so the early-strength quick-repair cement has positive meanings for the development of magnesian resources and the preparation of quick-repair cement in the future.
本发明提供了一种基于硫氧镁胶凝材料的新型快速修补水泥及制备方法，其特征在于，是由以下原料按重量份组成：轻烧氧化镁粉45~55份、硫酸镁溶液30~40份、标号为CA‑50或标号为CA‑70的铝酸盐水泥熟料2~7份、柠檬酸0.2~0.7份。本发明提供的一种基于硫氧镁胶凝材料的新型快速修补水泥，凝结时间短、早期强度高、稳定性好，在保证水泥的使用强度、抗渗性、稳定性等性能的前提下，同时降低成本，绿色环保，因此对未来镁质资源的发展和快速修补水泥的制备具有积极意义。
