Introduction. Calcium silicate is a group of compounds that can be composed of various ratios of calcium oxide (CaO) and silica (SiO 2), e.g., CaO·SiO 2 (CaSiO 3), 2CaO·SiO 2 (Ca 2 SiO 4), 3CaO·SiO 2 (Ca 3 SiO 5), and 3CaO·2SiO 2 (Ca 3 Si 2 O 7), which are derived from limestone and siliceous sedimentary rock [1].CaO–SiO 2 system …

In this paper, a comparative study has been made for physical and engineering properties of low calcium and high calcium Indian fly ash. The grain size distribution of fly ash is independent of lime content. Fly ash particles of size >75 μm are mostly irregular in shape whereas finer fractions are spherical for low calcium fly ash. For high calcium fly ash, …
