Fly Ash in Fiber Cement Process ?? Why not ???

The technology of replacing Portland cement with fly ash in fibre cement sheets offers numerous benefits such as ;
- Strength,
- Durability
- Resistance to chemical attacks.
Fibre cement sheets are widely used for shelters and are a versatile building material.
Cement which is a main component of the sheet fiber cement and the consumption is around an 1 millions ton annually in Indonesia.

Impact to CO2 ??

Consequently an 1 million tons of cement to usage in manufacture of sheet fiber cement of CO2 is emitted in to the atmosphere from cement manufacturing industries.

In Indonesia many power generation were using coal as source of energy and the waste end after process will be produced a fly ash.

Hence there is large potential for the use of fly ash in building products and in turn protect the environment by reducing Green House Gas (GHS) , reducing Emission and Global Warning.

Use of fly ash in cement, mortar and concrete as a pozzolanic material, saves the equal amount of cement, which otherwise would have been consumed.
The production of cement apart from being quite energy intensive also uses about 1600 kg of limestone and 400 kg of coal per tone of clinker.
Replacement of cement by fly ash also saves the corresponding amount of these natural mineral resources, which are already scarce ( on Limestone ). Further, reduction in usage of these minerals would also decrease the associated mining activity to the corresponding extent, hence the related environmental benefits

Action !
Usage the fly ash as your's material in Building Industries.
