Instead of being made with clay They are really designed with lime binding the silicate substance. The raw products for calcium-silicate bricks include things like lime combined within a proportion of about 1 to 10 with sand, quartz, crushed flint, or crushed siliceous rock along with mineral colourants. The elements are combined and still left till the lime is completely hydrated; the combination is then pressed into moulds and cured within an autoclave for three to fourteen hours to hurry the chemical hardening.[forty four] The completed bricks are extremely precise and uniform, Even though the sharp arrises want cautious managing to stop harm to brick and bricklayer.
