Calcium Silicate Hydrate
Calcium Silicate Hydrate, known as sand lime blocks or bricks are manufactured by mixing lime, sand, and enough water for the mixture to be molded.
They are then dried in an autoclave under high pressure {12-14 bar) and at high temperatures (160 – 200 C’).
These blocks & bricks are used for several purposes in construction industries, such as ornamental works in buildings, masonry works… etc.
Sand lime bricks are popularly used in Europe, India, and African countries.
Saudi Lime Industries Co. has been manufacturing blocks and bricks since 1977.
