Fly ash is primarily silicate glass containing silica, alumina, iron, and calcium. Minor constituents are magne-sium, sulfur, sodium, potassium, and carbon. Crystalline compounds are present in small amounts. The relative density (specific gravity) of fly ash generally ranges between 1.9 and 2.8 and the color is generally gray or tan.
This paper is focused on the utilization of pulverised coal fly ash as a raw mix component for portland cement manufacture. Among the ordinary cements, portland cement is the most important hydraulic binder. It consists of a blend of portland clinker with a small amount of gypsum (3-5%), as set retarder.

Fly ash bricks manufacturing has become a big money making business in India. Now people of India have slowly adapting the green brick technology (Fly ash Bricks) which is going to be a savior of our mother nature for years to come.
Class C fly ash can be used as a stand-alone material because of its self-cementitious properties. Class F fly ash can be used in soil stabilization applications with the addition of a cementitious agent (lime, lime kiln dust, CKD, and cement). The self-cementitious behavior of fly ashes is determined by ASTM D 5239.
The use of low-cost adsorbent has been investigated as a replacement for the current expensive methods of removing dyes from wastewater. As such, fly ash generated in National Thermal Power plant was collected and converted into a low-cost adsorbent. The prepared adsorbent was characterized and used for the removal of dyes from wastewater.
Fly ash is a fine, glass powder recovered from the gases of burning coal during the production of electricity. These micron-sized earth elements consist primarily of silica, alumina and iron. The difference between fly ash and portland cement becomes apparent under a microscope.
Application: Fly Ash Rubber Hose,tank, truck, Bulker loading/unloading or in-plant transfer of dry bulk cement, sand, lime, slurry etc., suction or discharge of abrasive materials. Construction: Lining : Uniform seamless tube of natural and synthetic blend rubber compound with excellent resistance to abrasion.

The extracted metals from the fly ash in the RDF incineration process generally exhibit relatively lower concentrations. However, testing fly ash revealed that both types of fly ash generated from burning MSW and RDF can be classified as hazardous materials due to higher heavy metal content. But the
Flyash bricks are light weight material compared to clay bricks, so it is suitable for multi storey building, Less weight means Less stress on building, safety assured. Low absorption of heat, FAB (fly ash bricks) absorbs less heat than normal bricks, it keeps your building cool even in summer, hence most suitable for Indian conditions.
Aug 02, 2016· Composition of Flyash: Depending upon the source and makeup of the coal being burned, the components of fly ash vary considerably, but all fly ash includes substantial amounts of silicon dioxide (SiO2) (both amorphous and crystalline), aluminium oxide (Al2O3) and calcium oxide (CaO), the main mineral compounds in coal-bearing rock strata.

Scaled down, pressed bricks were made from varying proportions of fly-ash, sand, hydrated lime, sodium silicate and water. Bricks of three distinct fly-ash to sand ratios were used, namely 50/50, 70/30 and 90/10, with varying amounts of sodium silicate (5, 10, 15, 20% by mass) and a 5% hydrated lime content.

The second method is carried out through fly ash fusion followed by a hydrothermal reaction as reported by several researchers [5, 9, 10]. In the fusion step, fly ash powder is mixed with fusion chemicals (NaOH or Na2CO3) and fused at high temperature (typically 550 oC) to convert fly ash into soluble sodium silicate and sodium aluminate.
