How to do brick masonry work?
Brick masonry is done with expertise. During masonry principle of masonry and joint should must be considered, otherwise the masonry will be weak and couldn’t be able bear the load. A brick masonry could failed due to cracks in vertical and horizontal joints. It is because of poor cement mortar ratio, dry brick laying and insufficient curing of masonry.
Selection of bricks for masonry:
Selection of bricks is done according to nature of construction projects. Whatever the selection but brick should be strong enough. Their colour and shape should be constant & proper. Their edges must be sharp.
The brick should be clean & plain. Shouldn’t have any crack on them. The compressive strength of A class brick is 105 kg/cm2 (1493 psi).
To check the quality of bricks? Collide/bump two bricks and the produced sound will be like melodious bell. Brick shouldn’t absorb more than 20% water to its weight while soaking it for 24 hours.
Stacking of bricks before masonry work:
Make a stacking of brick in proper manners near the construction place. Make sure while stacking and using the edges of bricks shouldn’t damage.
Soaking of bricks before masonry:
Bricks are soaked in water before 8 hours of their use. For soaking put them in to water tub or shower it very so often. Get them out of water before 30 minutes of use, so its surface can dry.
What is the purpose of brick soaking?
- To prevent Bricks from absorbing water content from mortar.
- It help to lay mortar with ease.
- Wet bricks make better joint with mortar.
- It cleans the bricks surface & remove the dust on it.
Preparation of mortar for brick work:
Prepare the mortar quantity with masonry work, which can be used in 30 minutes. In case of hydraulic lime the quantity should be prepared which can be used in 2 hours.
If anyhow the cement mortar can’t be used in 30 minutes and start setting, it shouldn’t be used with adding extra water and mixing again in anyway. Mortar ratio use for brick masonry is (1:4 to 1:6) but 1:6 is standard ratio.
What is unit weight of cement mortar? Unit weight of cement mortar is 2000 kg/m3.
For smaller projects mortar preparation is done with hands (a project where 1 or 2 masons are working on), while for big projects where number of masons work together, preparation is done with mixer machine.
Check》 To calculate mortar quantity.
Laying of bricks:
Brick masonry is done in a ordered sequence. This sequence of brick laying is called bond. There’s different bond in brick masonry, but if there isn’t any specific bond mentioned then English bond should be used.
Check verticality & horizontality of brick wall/column very so often. Wall/column should be straight. The horizontal & vertical joints between bricks shouldn’t be in continuous way nor on the top of bottom joint.
Masonry should be started from the corner. Masonry height shouldn’t exceed from 1.5 meter (5 feet) in a single day in anyway.
How many bricks are there in 100 cubic feet? There’s 1350 bricks in 100 cubic feet.
How many bricks are there in 1 cubic meter? There’s 500 bricks in 1 cubic meter.
Curing of brick masonry work:
There must be proper arrangement to protect fresh masonry from rain & hot weather. Masonry should be cure for at least 7 days.
Advantages of brick masonry work:
The use of bricks is consider suitable for construction work as compare to block or stone masonry, because it has more characteristics than other materials. Some of the properties of brick are follows.
- They have same size.
- While doing masonry, the mason has good grip for bricks.
- It cost less as compare to other materials.
- Locally available.
- Strong masonry because of better brick joints.
- It gives fascinated look to masonry.
- Bricks are strong and durable.
- For special work there are special bricks available.
- To bear the high temperature, fire bricks are available.
- For a shine surface, there are glazed bricks are available.
- It is also used for slab and floor construction.
Types of brick masonry bond?
There’re different types of bond in brick masonry.
This type of bond is used in half brick masonry, which is 4.5 inch (10 cm) wall. In this type, stretcher of bricks are on the front side of wall. There is to put a half brick bat at the start in all alternative layer to prevent the continuity of vertical joints.
This type is used in 9 inch (20cm) wall, which is made with a full brick. Only the headers of bricks are shown on front side of wall. In start of the layer a 3/4 piece of brick is used to prevent the continuity of vertical joints.
This is the strongest bond. This bond is used in 9 inch (20cm) wall. In this bond one layer is stretcher and the other is header and vice versa. This is the mostly use bond world wide.
If you wonder which bond should use in masonry? As English bond is strongest bond so it should be used in masonry work.
This bond is used in 9 inch (20 cm) or more thicker wall. In this bond both the stretchers and headers can be seen in a single layer from the front side of wall.
