Fly ash is also used as a component in the production of flowable fill. Used as the filler mineral in asphalt road laying to fill the voids. Fly ash is used as component in geoploymers. Used in Roller compacted concrete dams. Used in the manufacture of fly ash bricks When flyash is treated with silicon hydroxide it acts as a catalyst.
Fly ash/polytetrafluoroethylene material had potential as selfcleaning material. • Rolling of a water droplet on the dusty coated surface had collected the dust. • Spray coating is a costeffective technique to produce superhydrophobic surface. • 10 fly ash sample shows a contact angle of 147° and a sliding angle less than 10°. 1. Introduction
SelfCementing Fly Ash. Selfcementing fly ash mixed with water alone usually results in a very rapid time of set. Delays between placement and compacting of PSB material containing selfcementing fly ash are accompanied by a significant decrease in the strength of the compacted base material unless a retarder is used.
