Various amounts of pre-washed ash were added to replace the clay component of the raw materials for cement production. The allowable limits of chloride in the fly ash and bottom ash were found to be 1.75% and 3.50% respectively. The results indicate that cement production can be a feasible alternative for MSWI ash management.

22/11/2005  This paper describes the high-volume use of fly ash as a raw material in the manufacture of Portland cement. This approach provides three critical benefits to cement manufacturing and the environment. First, being rich in silica, alumina, and iron, the fly ash can essentially replace raw materials in cement raw feed, such as shale and clay, which are otherwise mined or purchased.

Fly Ash in Concrete Advantages Disadvantages of Fly ...

Fly ash is a fine powder that would be a by-product of the combustion of pulverized coal in power plants. Fly ash is a pozzolan, a liquid that contains aluminous as well as siliceous material which creates cement in the presence of water. When combined with lime and water, fly ash creates a similar composition to Portland cement.
