摘要
文章介绍了一种新型胶凝材料——矿渣—粉煤灰型地聚合物材料的物理力学性能,对该材料的某些关键性能进行了试探性研究。研究表明:用水玻璃作为地聚合物碱激发剂,其激发效果不如纯N aO H好;最佳原料配比是:矿渣和粉煤灰之比为4∶6,碱激发剂的最佳掺量为10%;地聚合物在水中的养护温度应高于30℃;Ca2+阳离子对地聚合物的强度起着重要作用。该材料作为油井的固井水泥浆和隔离用的地下连续墙建筑材料,已获成功应用,但在石油地面工程建设其他方面的应用,尚需进一步的探讨。
This paper introduces the mechanical and physical properties of a new type of cementitious material, i.e. slag-flyash type geqplymer. The results from probing into some key properties of the geoplymer show that the activating effect using water glass as a activator is not as good as using pure NaOH; the optimum proportion of slag to flyash is 4∶6 and the optimum blending ratio of alkali-activator is 10%;curing temperature of the geoplymer in water ought to be above 30℃; and cation Ca2+ plays an important role in geoplymer strength.
