Figure: Sand Lime. Bricks should contain a little amount of finely powdered lime. It enables silica (of a required portion) to melt at the furnace temperature of 1650 o C and binds the particles of brick together resulting in strong and durable bricks. At about 1100 o C, lime acts as a alyst to elevate the furnace temperature to 1650 o C at which silica fuses. This slightly fused silica ...

Bricks made from sand and waste plastic bottle (specimen PB) recorded highest compressive strength of MPa. However, normal clay bricks (specimen NB) presented a low compressive strength of MPa.
