BRICK
Bricks are small rectangular units made from clay,concrete,shale and others items. It is an important item used in construction of foundation, pavements,walls and other structures.
Bricks have been used for more than 7000 years.
Bricks are made from the clay obtained from ground . Water is added after removing all the impurities from the clay to form a consistent and smooth mixture. The prepared mixture is then put on a mold for the desirable shape. These bricks are generally known as green bricks have a alot of moisture . Thus they need to be sun dried .
After drying,the bricks are fired in klins at high temperature between 900°C to 1100°C to harden and give them strength .The final step is to let the bricks cool down to prevent cracks.All the bricks are sent for inspection to provide grade quality standards.
Features of good bricks are as folllows
•Hard and durable : Good bricks should be hard enough to resist water.
•Red or copper color : Proper deep color indicates proper burning.
•Uniform shape and size : Good bricks indicate equal sizes , surface and sharp edges.
•Low water absorption =They should now absorb more than 20 percent of water of their weight.
•Free from cracks and impurities : Good bricks have smooth surfaces and does not involve cracks,holes,stones and other defects.
•High compressive strength: Strength is the main objective of bricks. They should be able to bear heavy loads without breaking.

Facts about bricks:
1) Bricks are resistant to fire and extreme weather conditions.
2)Bricks regulate indoor temperature by providing good thermal insulation.
3)Bricks have different varieties in terms of color,size,shape and textures.
4)Well burnt bricks have high compressive strength and can support heavy loads.
5) Most type of bricks can be recycled and reused contributing to sustainable environment.
How to choose the right bricks.
1.Check the color it shout look like properly heated
2.Test the sound it should sound strong
3.Check Standard size and shape.
4.Check Water Absorption good quality bricks absorb water
5.Avoid overburn or underburn bricks
6.Soaking bricks before use.
7.Check for cracks abd defects.
8.Use the right brick for the right job as there are differnt types for every perpose.
