Brick Masonry

Brick Masonry

Bricks masonry is a form of construction performed by bricks with motar (mix of cement and sand), which are laid and arranged in different manners known as bonds such as Stretcher Bond, Header bond, English Bond, Flemish Bond.

These bonds are highly durable in construction of brick masonry.

Durable brick masonry walls are laid as one on top of another and the plumb is been checked to check the verticality of the wall. The Laying process defined as bonds, are different arrangements on placement of bricks resulting in durability strength and thickness of wall.

There are various types of brick Masonry work performed with fillers such as

• Bricks laid with mud 
• Bricks laid with motar

1) Brickwork with mud

• Soil Should contain clay of 10%- 20% to make is ideal for mud motar
• The Stress can be taken in dry condition - 1.5 to 4.0 N/mm2
• Stress it can take in wet condition - 1.3 to 3.3 N/mm2

Note - Moisture reduced compressive strength drastically

Application

• Construction should be done for only 1 floor and it should not be in seismic zone.

The advantage of this construction is, It is a cheap process and cement, aggregates are not required.

2) Brickwork with cement motar

    `

Cement motar is essential material to make bonding between bricks, The proportion of the bricks are considered on the area where we are going to use and so as the ratio is determined.

Normally the ratio varies between 1:4 to 1:7 in which one part is of cement and the other part is of sand.

The proper use of ratio increase effectiveness of the structure we are going to construct.

Following the there ration proportions usually considered.

• 1:4 mix - one part of cement and four parts of sand.

This proportion mortar is strong and is used for the construction of multi-storey buildings, building pillars, heavy or load effective walls, boundary wall and structures requiring high strength.

• 1:6 mix - one part of cement and six parts of sand

They are considered of medium quality and strength. This type of brick mortar is used for construction sites such as: two or three storey building, zones of heavy rainfall, and foundation of heavy/multi-storey building.

•  1:7 mix - one part of cement and seven parts of sand

Considered as average or normal strength. They are normally used in temporary structures, light walls and single storey construction etc.
