Calcium Silicate Blocks - 900x600 Mm, 600x150 Mm Sizes | High Thermal Resistance, Uniform Color Options, Versatile Applications In Industrial Environments

We manufacture, export and supply Calcium Silicate Blocks. The raw materials for calcium silicate bricks include lime mixed with quartz, crushed flint or crushed siliceous rock together with mineral colourants. The materials are mixed and left until the lime is completely hydrated, the mixture is then pressed into moulds and cured in an autoclave for two or three hours to speed the chemical hardening. The finished bricks are very accurate and uniform. The bricks can be made in a variety of colors, white is common but pastel shades can also be achieved.
