Fiber cement board are composed of cement, silica sand and wood pulp. reinforced fiber cement products such as fiber cement board are manufactured using the hatscheck process. the hatsheck process was initially developed for the production of asbestos composites, but it is now used for the manufacture of non-asbestos, cellulose fiber reinforced cement composites.
Cement and concrete basics. in its simplest form, concrete is a mixture of paste and aggregates. the paste, composed of portland cement and water, coats the surface of the fine and coarse aggregates. through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.
Cement manufacturing 1. cement cement is a finely ground, usually grey colored mineral powder. when mixed with water, cement acts as a glue to bind together the sand, gravel and crushed stone to form concrete, the most widely used construction material in the world 2. cement is typically made from limestone and clay or shale.
