Fly ash is used in about 50 of ready mixed concrete PCA 2000. Class F fly ash is often used at dosages of 15 to 25 by mass of cementitious material and Class C fly ash is used at dosages of 15 to 40 by mass of cementi-tious material. Dosage varies with the reactivity of the ash and the desired effects on the concrete Helmuth 1987 and
In the present study brick contains fly ash, Lime, water, and Quarry dust. Certain amount of the fly ash is substituted with Bagasse ash Table 3, this data from the Bagasse ash fly ash brick is than compared with that from a standard fly ash brick without bagasse ash. Five bricks samples of size 230 mm 115 mm 75 mm were cast.

Global Fly Ash Market Share revenue is poised to witness a substantial CAGR over the forecast time span. The Fly Ash industry share in North America is expected to witness a rapid growth during the time span, followed by Europe, Asia Pacific and Meddle East.
Fly ash is a coal combustion product.It is part of a set of products that makes up the most abundant waste materials worldwide. If not collected, this waste material is blown out with the flue gas in a coal fired power plant.Fly ash exists after combustion because ash adheres to coal, making up between 1-15 of its weight. About 90 of the ash is fly ash, while 10 is bottom ash.

Nigeria has large deposit of coal and clay. Fly ash is a by-product of thermal power plant. Coal firing power stations are therefore envisaged to be the main source of power generation in the country in the near future. Fly ash is produced by the injection of finely
specific gravity of the fly ash was 2.24, which was less than that obtained for cement. The loose bulk density and cocompacted bulk density of the fly ash were 1300 and 1418kgm3 respectively. The chemical composition of the fly ash is presented in Table 2. The result shows that the combined SiO 2, Al 2 O 3 and Fe 2 O 3
Nigeria Premium Members Gold Preferred ... Fly ash is useful in a number of ways and is one of the most researched upon mineral source.
