硅酸盐水泥强度增强添加剂的研究进展

Research progress in additives for strength reinforcement of Portland cement

硅酸盐水泥由于具有高的稳定性和生产成本较低等特点,广泛应用于民用和工业建筑。但是,由于其化学组成的固有特性导致其绝对强度并不高,甚至还会出现强度衰退的现象,从而限制了硅酸盐水泥的发展。研究发现,化学添加剂是增强硅酸盐水泥强度的一个有效策略。从无机、有机和新型功能材料这3方面对硅酸盐改性增强添加剂做了综述,并分析了其增强机理,为日后进一步优化硅酸盐水泥强度提供参考。

Portland cement is the most widely used in civil and industrial architectures fields, owing to its high stability and relatively low cost.However, its absolute strength is inferior even declines due to the intrinsic chemical composition.Then, the development of Portland cement was restricted.The chemical additive is an effective strategy to optimize mechanical properties of Portland cement according to relative studies.The strength reinforce additives of Portland cement were reviewed from three aspects Of inorganic, organic, and new functional materials, and their mechanisms were also analyzed, so as to provide a reference for the further improvement of Portland cement＇s strength in the future.
