Oxide Powder

Fly ash powder is a fine powder that is a byproduct of burning pulverized coal in electric generation plants. Fly ash is a pozzolan, a substance consisting of aluminous and siliceous material that creates cement in the presence of water. Fly ash forms a compound similar to Portland cement when mixed with lime and water. This makes fly ash acceptable as a prime material in blended cement, mosaic tiles, and hollow blocks, among other building materials.

Fly ash can be utilized as prime material in many cement-based products, for example poured concrete, concrete block, and brick. One of the most common uses of fly ash is in Portland cement concrete pavement or PCC pavement and in road construction projects using PCC can use a great deal of concrete, and substituting fly ash supplies significant economic benefits.

Fly ash itself is used by the power generating company producing the fly ash to enhance the economics of the overall disposal of surplus fly ash. Fly ash is applied to replace or displace manufactured cement. More modern manufacturing processes use a greater proportion of fly ash, and a high-pressure manufacturing technique, which creates high strength bricks with environmental benefits.

Fly ash powder: It may be utilized in combination with other alkaline materials to transform sewage sludge into organic fertilizer or biofuel.  There are several techniques for manufacturing construction bricks from fly ash, manufacturing a wide variety of products. One type of fly ash brick is manufactured by mixing fly ash with an equal amount of clay, then firing in a kiln at high temperature. This approach has the principal advantage of reducing the amount of clay required. Another type of fly ash brick is created by mixing soil, plaster of Paris, fly ash and water, and allowing the mixture to dry. Because no heat is required, this technique decreases air pollution.

Fly ash particles have proved their potential as good reinforcement with aluminum alloys and show the improvement of physical and mechanical properties; in particular, the compression strength, tensile strength, and hardness increase when the percentage of fly ash content is increased, whereas the density reduces. When employed in concrete mixes, fly ash improves the strength and segregation of the concrete and makes it easier to pump.
