This paper involves the study on the hardened and durability properties of the concrete at two different grades containing silica fume (SF) with various replacement percentages.
of MgO-microsilica paste. Thus MgO-microsilica pastes, which consists of 50%-90% MgO, 10%-40% microsilica and 2% sodium hexametaphosphate (in mass ratio), were prepared at water/solid ratio of 0.5, and these pastes exhibit excellent mechanical properties under ambient pressure, which indicates that the reaction of MgO and …
How microsilica improves concrete. Finer than fly ash, this pozzolan increases strength and density, reduces concrete permeability. Since microsilica particles are only about 1⁄. …
