碱度对少熟料低碱度钢渣水泥强度的促进作用

ACTIONS OF ALKALI CONTENTS AND pH IN THE SOLUTION ON CEMENT STRENGTH OF STEELSLAG WITH LOWER ALKALI BASICITY AND A FEW OF CLINKER

本文讨论了碱和液相碱度对少熟料低碱度钢渣水泥强度的促进作用。结果表明：水化液相具有高碱度和富Ｎａ２ＳＯ４的水化环境将促进低碱度钢渣和矿渣的水化，高Ｃ３Ｓ适量Ｆ—ＣａＯ的立窑熟料能显著改善少熟料低碱度钢渣水泥体系的早强和后期强度性能。

Actions of alkali contents and pH in the solution on cement strength of steelslag with lower alkali basicity and a few of clinker have been discussed.It has been reported that the hydrating surrounding with higher pH and richer Na2SO4 contents in the aqueous solution can favor the hydration of steelslags.Meanwhile,the clinker from shaft kiln with higher C3S contents and suitable contents of FCaO can improve early and later strength of cementin the system.
