摘要
双掺、三掺方式可以保证混凝土在大掺量矿物掺合料条件下仍具有良好的工作性、较高的强度 ,同时还可以显著提高硬化混凝土密实性 ,有效改善水泥石 集料界面区结构 ,从而减少了硬化混凝土中未水化水泥数量 ,抑制了外界水分的渗入 。
Double_adding and tri_adding mineral admixtures can provide concrete containing large quantities of mineral admixtures with better fluidity,and higher strength and it greatly improve compaction of harden concrete and the cement paste_aggregate interfacial structure. As a result, the cement unhydrated in harden concrete has been reduced, the penetration of exterior water has been restrained, and the damage caused by the further hydration of cement unhydrated is finally eliminated.
