Brick is a block of ceramic material used in building construction. Bricks are typically stacked together as a wall using cement/plaster. These components hold the brick together and make them a permanent structure- wall. There are different types of brick made with different material like Clay brick, C4x and Solid block/Fly Ash brick.

Factors Clay Brick Flyash C4X

Weight and strength Heavy and losses strength if any manufacturing fault Light weighted then clay and stronger Much light weighted and stronger than others. Older the blocks stronger they are.

Application Partition, Insulation, low rise load bearing and non-load bearing walls Load bearing and non-load bearing walls Load bearing and non-load bearing walls
– – – –
Thermal Conductivity Low thermal conductivity – Lowest thermal conductivity & therefore interiors stay cool in summer and warm in winters.

Size and Shape 4” & 6”,
non-feasible 		4” and 6”,
non-feasible 		4”,5”, 6”, 8”. Can be caste in any shape and size and density
