摘要
介绍了粉煤灰、硅灰、纳米硅以及复合微粉对C3S水化的作用,对其产物的显微结构进行了分析。结果表明:不同粒径的微粉与C3S 二次水化反应时,在Ca(OH)2的侵蚀作用下,早期生成絮状C-s-H凝胶,后期生成向外呈辐射状的纤维c-s-H。这种二次水化产物可 填充不同粒径颗粒之间的孔隙,最终形成致密网络状的二级界面显微结构。
The hydration reactions of C3S and three types of superfine powder materials and the microstructure of the hydrated pastes were studied. The results show that when the secondary hydration between micro-powders and C3S happened, flocculent C - S- H formed in the early hydration and the C - S - H with outward rediatiform fibres at later ages. These secondary hydration products can fill in pores among different size particles and the secondary interface microstructure with compact network figure forms as a result.
