Fresh concrete including silica fume is more cohesive and less liable to segregation than concrete without silica fume. As the silica-fume content increases, the concrete might appear to be viscous. Concrete con-taining silica fume demonstrates considerably reduced bleeding. This effect is primarily due to the high

This study reports the effect of silica fume on alkali leaching and efflorescence formation of alkali-activated slag. ... and reaction products. AACs are produced from the reaction of aluminosilicate powder as precursor with strong alkali solution, which results in the formation of amorphous N ... C-S-H in alkali-activated slag …

With the addition of 20% silica fume, the 7 d and 28 d compressive strength were 22.2% and 34.3% higher than those of mixes without silica fume, respectively. This different effect of SF on the compressive strength (of mixes with different CAC contents) will be further explored by analysis of their microstructure in Section 4.1 .

Using 10% sand, 10% cement amalgam, and 20% MPW, Ashish's research on concrete mixtures with marble powder in place of cement and sand revealed that marble powder was a workable substitute 20,21.
