• Iron Oxide : Imparts red colour to the bricks

• Magnesia : Imparts yellow tint to the bricks

and decrease

shrinkage

• Lime : Prevents shrinkage of raw bricks

• Prevents cracking and shrinking• Durability of bricks

Basic Composition of Clay Brick

• Imparts plasticity to the clay so that it can be moulded

SUITABILITY- Structural uses : such as foundations walls and floors

- As a decorative feature

- Interior : Used for Fireplaces and chimneys

- Suitable of Exterior wall : Good compressive strength

- Commonly used in construction up to FOUR storeys

CLAY BRICK

CLAY BRICK WALLADVANTAGES DISADVANTAGES

Aesthetic appeal Time consuming construction

Thermal & Acoustic insulation Cannot be used in high seismic zones

Less maintenance costIt does not rot, dent or need to be painted

Very less tensile strength

Fire resistance Rough surfaces of bricks

Flexible in application Hard to clean the surface of the bricks

Never tear or be eaten by termites
