摘要：

Effect of fly ash, slag, silica fume, nano-SiO2 and nano-CaCO3 on water demand of cement paste with was studied in this paper. The results showed that the water demand of cementitious increased with the replacement ratio increasing for fly ash, silica fume and nano-particles, but decreased for slag. The change of water demand was not changed obviously with silica fume under 8%. The water demand increased slightly with nano-particles under 2%, and increased sharply as replacement higher than 5%.
