摘要
本文通过用XRD测定晶格畸变与晶粒大小,XPS测定电子结合能,FT—IR和Laser Raman法测定结构基团振动谱及微热量热法测定早期水化速率探讨了掺杂β—C_2S的微观结构与性能之间的关系。指出掺杂β—C_2S的晶格和SiO_4^(4-)团发生畸变、无序度增加、晶粒细化、电子结合能化学位移是其活性提高、水化加速的根本原因。
The relationship betrween microstructure and properties of doping β—C_2S was discussed on re-sults of determination by means of XRD、XPS、FT—IR and Raman as well as microcalorimetry. Itwas shown that activity is increased and hydration is accelerated because of the lattice and [SiO_4]^(4-)deformations and the crystal disorders and the fine grains as well as the binding energy shifts of dop-ing β—C_2S.
