Jan 24, 2016 The fly ash concrete is more workable and less water is needed for the same slump. Although increased fineness usually increases the water demand, the spherical particle shape of the fly ash lowers particle friction and offsets such effects. The use of fly ash as a partial replacement for Portland cement will usually reduce water demand.Jan 24, 2016 The fly ash concrete is more workable and less water is needed for the same slump. Although increased fineness usually increases the water demand, the spherical particle shape of the fly ash lowers particle friction and offsets such effects. The use of fly ash as a partial replacement for Portland cement will usually reduce water demand.State-of-the-art report STAR on alternative pozzolans is a review of the use of unusual supplementary cementitious materials in concrete. Materials that are included in this report are micro-LWA, calcined clay, rice husk ash, nano-silica and glass. Common ones like silica fume, fly ash, slag and metakaoline are only mention as comparison.Pond ash Fly ash and bottom ashes are mixed together with water to form slurry which is pumped to the ash pond area. In the ash pond the, ash gets settled and excess water is decanted. This deposited ash is pond ash. 1.2 FLY ASH Fly ash is a fine, glass powder recovered from the gases of burning coal during the production of electricity.Fly ash can make concrete more durable, particularly to mitigate alkali-silica reactivity ASR and sulfate attack. Fly ash reduces the CO2 footprint of concrete and reduces the embodied energy. Using fly ash in concrete reduces disposal in landfills and address the issue of high potential hazard to groundwater contamination.
