approximately 10% water, strong fly ash brick can be produced at compaction pressure of 3,000 psi, approximately. The bricks produced, upon two weeks of curing, have compressive strength exceeding that required by ASTM for ordinary bricks. The fly ash bricks also have good water absorption property and low permeability.
The properties of fly ash from co-combustion depend greatly on the burning conditions (the kind of boiler, tem-perature of burning), the amount and chemical composition of the ash from coal and biomass, as well as the share of the biomass in the mixture with coal.
Fly ash. Fly ash, also known as "pulverised fuel ash" in the United Kingdom, is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases. Ash that falls to the bottom of the boiler is called bottom ash.

Fly ash, major raw material of fly ash brick, is the by-product of thermal power plant, our fly ash plant is able to make comprehensive utilization of fly ash. Material Preparation Fly ash aac plant is a steam cured mix of fly ash, cement, lime, water and Aluminum powder.
Fly ash produced thus possesses both ceramic and pozzolanic properties. When pulverised coal is burnt to generate heat, the residue contains 80 per cent fly ash and 20 per cent bottom ash. The ash is carried away by flue gas collected at economiser, air pre-heater and ESP hoppers.
Fly ash can be used as prime material in many cement-based products, such as poured concrete, concrete block, and brick. One of the most common uses of fly ash is in Portland cement concrete pavement or PCC pavement.

Fly ash is comprised of the non-combustible mineral portion of coal. When coal is consumed in a power plant, it is first ground to the fineness of powder. Blown into the power plant’s boiler, the carbon is consumed — leaving molten particles rich in silica, alumina and calcium.
A mixing proportion of 50% fly ash produces a brick with minimum water ab- sorption. Since the bricks contain incompletely burned coal, on burning, the brick is burnt from the outside in-
Boiler tubes extract heat from the boiler, cooling the flue gas and causing the molten mineral residue to harden and form ash. Coarse ash particles, referred to as bottom ash or slag, fall to the bottom of the combustion chamber, while the lighter fine ash particles, termed fly ash, remain suspended in the flue gas.
However, fly ash has rarely been applied to bricks. In our research we use ash as a potentially suitable organic material and also as inert material.
