Mining companies argue that the body can clear chrysotile asbestos fibers from the lungs and that as a result, chrysotile asbestos poses no health risk. In a paper titled "Undeniable Facts about Chrysotile," its proponents claim that not only does chrysotile have less risk than other forms of asbestos, but also that at low exposure levels, it produces no risk at all. Doctors and scientists counter with the statement that all forms of asbestos cause cancer. According to, a site about asbestos-related cancers, doctors say no amount of asbestos of any form is safe. In 2007 Occupation and Environmental Medicine published a follow-up study of chrysotile asbestos textile workers in South Carolina. The doctors and researchers concluded that the study confirmed the findings from previous investigations of increased risk of death from lung cancer and asbestosis and a strong correlation between exposure to chrysotile and mortality from lung cancer and asbestosis

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.

Reduce Waste Sack Kraft Cement to Waste Newsprint Paper

Ideas !
- Long Fiber will be countinues to supply ?
i.e UNBKP , Waste Sack Kraft Cement
- Supply and demand of Long Fiber Cellulose from Fiber Cement Manufacture.
- Price of UNBKP and Waste Sack Kraft Cement.

Action !
- Reduce of Long Fiber Cellulose from UNBKP or Waste Sack Kraft Cement to other waste paper
i.e Newsprint.
- Reduce the density of Sheet products

Why Waste Newsprint ?
- Stability of fiber composition in the sheet paper of newsprint comparing other waste paper.
- Availabilities compare to Waste Sack Kraft Cement.
- Bulky , So the density of Fiber Cement Products will be reduced , will be effected to total cost
of manufacturing.

Have tried and good results
Application to Non Asbestos Flat Sheet 3.5 mm ( air cure )
Roofing 3.5 mm ( air cure )

How To Protecting Organic Fiber - Cellulose Fiber from Alkalinity Cement ?

Cellulose Fiber Was Protected with Anti Alkalinity ( MAK-AA ).

Chemically treating cellulose fibers to impart the fibers with hydrophobicity and/or durability, and making cellulose fiber reinforced cement composite materials using the Chemical / Additive MAK-AA treated cellulose fibers which the cellulose fibers are treated or covering / protected with specialty chemicals MAK-AA that impart the fibers with higher hydrophobicity by partially or completely blocking the hydrophilic groups of the fibers.

This technology advantageously provides fiber cement building materials with the desirable characteristics of reduced water absorption of Cellulose Fiber have advantage reduced rate of water absorption which content of Alkalinity components from cement, which was lower water migration will be impacted to lower water permeability so the final products made from these materials have improved freeze-thaw resistance, reduced efflorescence, reduced dissolution and re-deposition of water-soluble matrix components in natural weathering.

Using MAK-AA almost to improve other product properties to the physical and mechanical of final product.

As results of using MAK-AA i.e the bending strength was increased 10 - 12 % with using 0.05 % of MAK-AA from total weight.
Data was taken from Flat Sheet Calsium Silica Board Product.
