Bricks are a specialized instrument of building construction made by clay, sand and concrete. Depends on the raw materials and burning pattern there have different types of bricks used in different perspective.
The durability, strength and hardness of bricks depends on different types of bricks. A good bricks have following properties.
Hardness : The high hardness brick have long lasting existence and highest durability. It have less wear and tear.
Compreasive strength : The high compression resistance strength of bricks are suitable for load bearing construction.
Absorption : Low water absorption of bricks are suitable for construction because it shows low cracking and tearing as well as shows low hydrophilic nature in water exposures.
Thermal conductivity : Bricks with low thermal conductivity have high insulation capacity.
Efflorescence : The deposition of white spot on the bricks due to salt. It weakens the bricks.
Alkali resistance : Bricks with high alkali resistance have less degrading property.
Physical properties of good bricks
Size: 8.5 inch 4.5 inch product 2.75 inch bricks are good in size.
Color : Smooth surface and sharp edge bricks are good for load bearing construction.
Sound : While the high quality bricks are tapped it produces ringing sound.
