摘要：

This paper presents the results of an investigation into the effects of ultra-fine materials on workability and strength development of concrete containing alkali-activated slag (AAS) as the binder. It was found that partial replacement of slag with ultra-fine fly ash significantly improves the workability; however, the strength development is similar to ordinary portland cement (OPC). Partial replacement of slag with condensed silica fume (AAS/CSF) and ultra-fine slag (AAS/UFS) show significantly greater strength than AAS at ages greater than one day. However, AAS/CSF has high water demand whereas AAS/UFS has minimal loss of workability compared with AAS. (C) 1999 Elsevier Science Ltd. All rights reserved.
