studied the properties of SCC made with low calcium fly ash (Class F). Nuruddin et al. (2010) explored the workability, strength and durability characteristics in a selfcompacting concrete containing fly ash as partial replacement for cement. Fly ash addition into the concrete enhanced the workability and strength of the concrete.

Silica fume is the finest with most particles averaging µm (microns), metakaolin averages about 4 µm, Portland cement averages about 15 µm, and fly ash about 70 µm. Many pozzolans are waste products from industrial processes. Fly ash comes from coalfired power plants, and silica fume and slag comes from some steel refineries.

Alternative Cement . Project Drawdown defines alternative cement as: the use of an increased percentage of fly ash instead of Portland cement in practice replaces the use of conventional concrete made primarily of Portland cement. During 2010, gigatons of carbon dioxide was released as a result of cement production (Boden, Andres Marland, 2013).
