Aug 28, 2018· Cement Manufacturing Process. Cement is the basic ingredient of construction and the most widely used construction material. It is a very critical ingredient, because only cement has the ability of enhancing viscosity of concrete which in returns provides the better locking of sand and gravels together in a concrete mix.
The fly ash, if added to the cement manufacturing process at either of these two points, remains fly ash and although thoroughly blended into the portland cement will perform about the same functions in concrete as if it were added later by being blended with other ingredients during the concrete manufacturing process.
The use of fly ash, a recovered resource, reduces the depletion of natural resources. It also reduces the energy intensive manufacturing of portland cement. This reduction in energy leads to less emissions of greenhouse gases. The use of a ton of fly ash to replace a ton of cement saves enough electricity to power an average american home for ...
indicated that fired bricks made from feeds of 72% flyash, 25% bottom ash, and 3% sodium silicate met commercial specifications. It is also worth noting that recently India has been leading the way in flyash brick manufacturing.
