在成型前对新鲜地聚合物进行离心预处理是提高地聚合物基体抗压强度的有效方法。研究了不同离心速度下地聚合物基质的微观结构和性能。采用1000 rpm离心分离法制备了孔隙分布和排列结构优化的增强地聚合物基质，其抗压强度比原始基质提高了70%。综上所述，我们设想，当考虑到实际应用时，该方法可以为大型离心机优质地聚合物基质的设计和制造提供一种创造性的策略。
The pretreatment of fresh geopolymer by centrifugation before moulding was verified to be an effective method to improve the compressive strength of geopolymer matrix. The microstructure and properties of geopolymer matrix were investigated with different centrifugal speeds. A reinforced geopolymer matrix with optimizing pore distribution and arrangement structure was developed by 1000 rpm centrifugation, which presented a 70% increase in compressive strength compared with the pristine matrix. In summary, we envisage that this method could provide a creative strategy for the design and fabrication of superior geopolymer matrix for large centrifuge when considering the real application.
