As pozzolan greatly improves the strength and durability of concrete, the use of ash is a key factor in their preservation and add to the concrete's final strength and increase its chemical resistance and durability.It can also increase workability of cement while reducing water demand. The replacement of Portland cement with fly ash also reduces the greenhouse gas foot print of concrete, as the production of one ton of Portland cement produces approximately one ton of CO2. Since the worldwide production of Portland cement is expected to reach nearly 2 billion tons by 2010, replacement of 30% of this amount by fly ash could dramatically reduce global carbon emissions.

What do you add to fly ash to make cement?
Fly ash is an ingredient in cement manufacturing. The main components of cement are limestone, clay, sand, and fly ash. The cement folks are interested in the silica and alumina in the fly ash, so depending upon the amount of those in the fly ash allows them to decrease the amount of clay and sand which is where they get those constituents if they don't use fly ash. The advantage is to decrease the volume of clay and sand that have to be mined, realizing a cost savings as well as saving the clay and sand for future generations.
What is the function of the cement?

What is pozzolanic cement?
Pozzolanic cement is a cement which consists of pozzolanic materials like fly ash, volcanic ash, pumicite,etc.,A Pozzolan is any material which in the presence of lime and water will react hydraulically to form a cemented massContains pozzolanic materials of 10-95% by weight.Pozzolanic cement can be made from 95 % recycled materialsprovides many improved performance ove OPC. (ordinary portland cement)It is generally used now a daysLess heat evolved when compared to OPC.

What is fly ash how can you earn wealth from it?
Fly ash is a common term for the final product of coal after combustion. The white ash has properties similar to portlan cement. Since portlan cement is a comon binder in concrete it has a multitude of construction applications. The way you can earn wealth from Fly ash is to sell the ash too the concrete market. Fly ash is rate based of of it's composition though and it's composition is based off of the product combusted to produce it. Hope this helps and yes it is harmful to the enviroment...i think :)
