calcium carbonate (limestone)
Limestone
Clay triangle is used to hold a crucible while the crucible is heated.
hydraulic cement, after the combination is grind ed into a fine powder!
Most cements are made from a mixture of pulverized limestone and clay, so technically it is made out of rock.
Limestone is roasted to make lime (calcium oxide) or slaked lime (calcium hydroxide).Other materials and rocks added during roasting are clay, shale, sand, iron ore, bauxite, fly ash, and slag which provide alumino-silicates.
you can simply isolate your house by changing your brick walls to tyres and instead of cement a mixture of clay and straw and mud
Cement
clay + limestone = cement
Actually, nothing is heated to create cement. Cement is a mechanically bonded combination of cement, sand, water, and gravel (aggregate).
it is mixed with clay to form cement.
a toliet is made with clay and the clay is heated to make it harden
Clay makes bricks. Sand is used in cement.
carbondioxide
calcium carbonate :)
you make it by mixing limestone powder and clay in a kiln
Combine clay and limestone to make cement.
Powdered limestone has to be heated with powdered clay to turn it into to cement. You can then use cement and powder it, then mix with water, sand crushed rock and a slow reaction takes place forming concrete. It is in the Cors Science GCSE
