C_(11)A_7·CaCl_2和3C_2S·3CaSO_4·CaF_2的水化性能研究

STUDY ON HYDRATION OF C 11 A 7·CaCl 2 AND 3C 2S·3CaSO 4·CaF 2

合成了Ｃ１１Ａ７·ＣａＣｌ２和３Ｃ２Ｓ·３ＣａＳＯ４·ＣａＦ２两种矿物，借助ＸＲＤ，ＳＥＭ等测试手段，研究了这二种矿物及其以１∶１掺合时的水化历程。结果表明，矿物３Ｃ２Ｓ·３ＣａＳＯ４·ＣａＦ２水化能力较弱，但与Ｃ１１Ａ７·ＣａＣｌ２共掺时，其水化活性可以大大地得到激发。

In this paper,two minerals C 11 A 7·CaCl 2 and 3C 2S·3CaSO 4·CaF 2 are synthesised.Using XRD,SEM,TGDTA methods,the hydration processes of each of these minerals and mixture of them(each in 50%)are investigated.Results reveal that hydration of 3C 2S·3CaSO 4·CaF 2 is carried out slowly,and can be effectively activated by adding C 11 A 7·CaCl 2.
