摘要
研究了掺杂 ＴｉＯ２对Ｃ２Ａ３Ｓ矿物的形成及水化性能的影响在１３００℃保温１ｈ， ＴｉＯ２稳 定过渡产物ＣＡ的作用使Ｃ４Ａ３Ｓ的形成速度降低；在１３００℃保温３ｈ，适量的 ＴｉＯ２增加 Ｃ４Ａ３Ｓ的 形成量；ＴｉＯ２的含量过高，使Ｃ４Ａ３Ｓ的形成量减少并出现 ＣＴ（ＣａＴｉＯ３）．掺杂ＴｉＯ２使Ｃ４Ａ３Ｓ 以四方晶系的结构存在掺杂提高了Ｃ４Ａ３Ｓ的水化反应活性。
The influence of TiO2 on the formation and hydration properties of C4A3S were studied. Results showed that the forming speed of C4A3S decreased because TiO2 stabilized the transitional product CA at 1300℃; increasing soaking time to 3h, a suitable amount of TiO2 increased the content of C4A3S; and higher content of TiO2 decreased the content of C4A3S and formed the mineral of CT(CaTiO3). TiO2 resulted in the appearence of C4A3S crystal of tetragonat structure. TiO2 increases the hydration acticity of C4A3S, this can be attributed to the distortion of crystal lattice of C4A3S.
