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.
Implementation.
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.

Quebec asbestos mine may close in 2012

A confidential federal memo suggests Canada's last fully functional asbestos mine is about to die, raising the prospect the controversial industry might just disappear on its own.
The Natural Resources Canada memorandum, released under the Access to Information Act, estimates that the life of Quebec's Lac d'amiante du Canada will end in early 2012.
This information sheds new light on the international argument over asbestos and suggests that, despite its loud defence of the industry, the Harper government is aware it could die a quiet death.
The vast majority of Canadian asbestos exports come from the facility in Thetford Mines, Que; investors are also hoping to save another mine in nearby Asbestos which has operated infrequently in recent years.
Canada's asbestos industry has nearly disappeared in recent decades amid concerns about the substance's cancer-causing properties. Its opponents call it immoral that Canadians still export to poor countries a product they would not use in their own homes.
But the federal government's own assessment is that the main mine could be gone within months.
"The open-pit Lac d'amiante du Canada (LAC) operation will be the last remaining chrysotile mine in Canada, with an estimated mine life of two to four years," said the February 2008 assessment.
The Canadian Cancer Society says more than 100,000 people die worldwide every year from occupational exposure to asbestos and a growing chorus of health experts have repeatedly called on Canada to stop exporting the mineral.
But the warnings have not changed Ottawa's position on the fibrous mineral.
Last month, the Conservative government steadfastly refused to let the substance be added to an international hazardous-chemicals list -- a United Nations treaty known as the Rotterdam Convention.
The long-held position of the Tories, and other asbestos industry supporters, is that it's safe when handled properly.
Defenders of the industry also credit it for creating hundreds of jobs in the economically depressed region of central Quebec, a point the Conservatives have tried to translate into votes.
Prime Minister Stephen Harper has visited the heartland of Quebec's asbestos industry twice in recent months, including a stop during the federal election campaign. He also chose to celebrate Quebec's Fete nationale holiday in that region.
But is the prime minister's support a moot point?
The federal document surfaces at a critical juncture for the future of Lac d'amiante and, by extension, for the Canadian asbestos industry as a whole.
This week, LAB Chrysotile, the company that manages the mine, said it might shutter the operation indefinitely this November. The closure could effectively halt Canada's active asbestos mining industry.
But company president Simon Dupere insisted the current problems have nothing to do with shrinking deposits of chrysotile buried beneath Thetford Mines.
He said the mine could continue to scoop asbestos out of the ground past 2012, but he declined to specify for exactly how long.
"No, it ain't the case, it's not going to be over by 2012," Dupere said, adding the federal document probably focused on just the proven reserves.
"There's enough resources to last way longer than that... Thetford Mines is full of it. No matter where you look, you could dig and find some."
Dupere blamed the possible closure of the operation on "internal challenges."
"It is labour, it is production, it is development, it is a bit of everything," he said.
The miners' union is banking on the company to overcome these issues to save jobs.
The president of the local branch of the United Steelworkers, which represents the employees, is concerned the mine's closure could put 350 people out of work.
Luc Lachance was surprised to hear that Ottawa believed the mine might run out of asbestos by 2012. He said he was told there's still two and a half years of life left in it.
But he added that for the mine to live on, it needs the provincial government's permission to dig under a closed highway.
"If it goes well, we'll continue, and if it doesn't, they'll close it," he said.
The Quebec government is already holding one shovel that could help the declining industry dig out a future.
The province is considering whether to help revive Canada's only other asbestos operation — the mostly mothballed Jeffrey Mine, which has only been extracting chrysotile sporadically in recent years.
Quebec is prepared to give a $58-million bank-loan guarantee to Jeffrey Mine, as long as it can come up with $25 million from private investors by Aug. 15.
Local asbestos advocates say the financing would relaunch Jeffrey, located in the town of Asbestos, for another 25 years and create 500 jobs.
The Natural Resources memorandum was released under the Access to Information Act and given to The Canadian Press by Kathleen Ruff, a prominent asbestos industry critic and human-rights activist.
A spokeswoman for Natural Resources Canada confirmed the document's authenticity.
