What is a Building material made from cement and asbestos mainly used in Australia?
the use of asbestos in buildings in the UK started around 1890, the used of Blue and Brown asbestos was banned in 1985, with White asbestos being banned in 1999.
Up until 1976 it was required in a lot of buildings where fire resistance was necessary.
To make cement, well concrete actually, you start with Portland Cement. It contains calcium silicates, "aluminum and iron containing clinker phases" and "other compounds." You… add some calcium sulfate to adjust the setting time, and you've got it. Once you have that (if you're doing this in school for a science project forget about making your own; you need a kiln you don't have to make this. Oh, and you can get 94 pounds of it for less than $8 at any lumber yard in the country) add one part cement, two parts sand and three parts gravel plus just enough water to make a product that will stick together if you grab a handful and squeeze it. There are a LOT of "admixtures" that can be put into concrete. You can use latex, chopped fiberglass, chemicals to make it harden faster or slower, just lots of things. But Portland cement, sand and gravel are the most important parts. Even concrete that doesn't "look" like there's gravel in it, has gravel in it.
Glass, Cement, Concrete and Mortar can be made from limestone. . Hope that answers your question, thank youuuuu :)
The materials used to make cement are, . Calcareous materials (limestone) . Argillaceous materials (clay) . gypsum . Coal dust . Iron oxide . magnesium . Alkalies
why is basalt used as building material
It is probably not a good idea to install new asbestos pipe. Asbestos pipe requires remediation if and when it deteriorates to that it may be releasing asbestos fibers.. Whet…her it is legal to install asbestos pipe depends one what legal jurisdiction you are in. Some countries have forbidden all use of asbestos containing products and some permit some uses to continue.
It was made for many years until it was found to be deadly, around the seventies. There is still plenty in situ. and great care must be used in handling it.
Asbestos is still being mined, processed, and used in Russia, Brazil, China, and India. It is being used mostly in cement products, and some electronics.
Any asbestos containing product can be harmful if it is used or abused in a way that results in the release of excessive quantities of fibers to the air. If the product is not… used or abused to accomplish that, then it is not harmful.
I don't know when it was first used. I do know that it is now considered a chemical that is lethal to our health.
not exactly, you can use it for holes on the road, but mainly for construction.
There are a number of forms of asbestos that can be called by a colour, but can also be called by their actual mineralogical or trade name. White asbestos, which is more prop…erly called Chrysotile, was widely used in building products and is the most commonly found type of asbestos in building materials today. However, other types have also been used. Brown asbestos, more widely known by its trade name, Amosite, is the second most commonly found asbestos type in building products.
Prior to about 1975, asbestos was a common material in insulation around pipes and boilers in Navy Ships.
