Sand lime bricks:
These are very strong & hard bricks. Sand for these should be coarse (but not very coarse), clean, free from salts or organic matter, with grains of assorted sizes, & well graded so as to have min voids. Lime to be well burnt, free from ashes. It should be a high calcium lime, containing 90-90% of Cal. oxide & not more than 0.5% of magnesium oxide & filled in moulds. The moulded bricks are then placed for hardening in a closed cylinder called Autoclave for 10 hrs. Generally, the bricks are moulded by day & left over night to harden. The lime is slaked & intimately mixed with sand in proportion of 4-10%. Sand-lime bricks are much stronger than clay bricks & are uniform in color & texture.

To safeguard against crack formation, skin reinforcement is designed on the side faces of deep beams to limit the formation of flexural crack widths. Though the principal function of skin reinforcement is to control crack width, it may be employed for providing bending resistance of the section.
