This invention relates to a method for making an asbestos-free calcium silicate board, which comprises preparing a slurry of a mixture of silicic acid material, lime material, fibrous wollastonite and pulp with a large amount of water, forming the slurry into a raw board by means of the sheet-forming technique, steaming the raw board and drying.
Material description. The term "cement" originates from the Latin word "Caementum", which signifies chopped stone.Cement describes a substance which will react chemically with water and develop into a material hard as stone.. In fibre cement there is a fibre reinforcement, which contributes to making the fibre-cement material even stronger.

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.
Asbestos fiber semen technology About 120 years ago, Ludwig Hatschek made the first asbestos reinforced cement products, using a paper-making sieve cylinder machine on which a very dilute slurry of asbestos fibers (up to about 10% by weight of solids) and ordinary Portland cement (about 90% or more) was dewatered, in films of about 0.3 mm, which were then wound up to a desired thickness ...

High-Strength Concrete. In the early 1970s, experts predicted that the practical limit of ready-mixed concrete would be unlikely to exceed a compressive strength greater than 11,000 pounds square inch (psi). Over the past two decades, the development of high-strength concrete has enabled builders to easily meet and surpass this estimate.
