CaF2对阿利特-硫铝酸锶钙水泥性能的影响
Effect of CaF2 on the Performance of Alite-strontium Calcium Sulfoaluminate Cement
摘要
Abstract
Alite-strontium calcium sulphoaluminate cement, a new type of cementitious material is synthesized by combining strontium calcium sulphoaluminate with minerals of Portland cement. The influence of CaF2 on the synthesis and performance of the cement is studied by XRD, SEM-EDS, and lithofacies. The results show that suitable amount of CaF2 can benefit f-CaO combination and promote the formation of alite and strontium calcium sulphoaluminate at low temperature. The optimal mass fraction of CaF2 is 0. 6%. The compressive strength of the cement prepared under these conditions reaches to 32.8 MPa, 67.7 MPa and 120.4 MPa at 1 d,3 d and 28 d.关键词
