研究了CaF2 对C4A3S矿物形成及水化性能的影响 .结果表明 :掺加少量的CaF2 ,C4A3S矿物的形成量能增加 ,而当CaF2 掺量为 1 % (质量分数 )时 ,C4A3S的形成量则减少 ;CaF2 的存在使C4A3S矿物晶体主要以四方晶系的结构形式存在 ;少量的CaF2 不仅可提高C4A3S的水化反应活性 ,而且还影响水化产物晶体的形貌
The influence of CaF 2 on the formation and hydration properties of C 4A 3S was studied. Results showed that the product of C 4A 3S can increase by adding a suitable amount of CaF 2, but if the amount of CaF 2 is 1.0%, the product of C 4A 3S decreases. Addition of CaF 2 will result in the crystal of C 4A 3S existing in tetragonal structure mainly. At this experimental condition, a suitable amount of CaF 2 can increase the hydration activity of C 4A 3S and change the morphology of hydration product crystal.
