Concrete Blocks

 Concrete Blocks 

Today  I give  some knowledge about different types of blocks which can be used in masonary work . These Blocks are eco friendly.

• Blocks have high compressive strength.
• These have high thermal efficiency. External walls made up by  these Blocks keep the rooms cool .These can not allow External heat to enter inside.
• Concrete Blocks also reduce the construction time and cost.
• These can enhance  quality  of construction also.
• These also have dimensionl accuracy.
• The air in the hollow blocks does not allow outside heat or cold to pass. So It keeps cool in summer and warm in winter.These maintain temperature and save electricity.

• Blocks are light in weight, easy to use.
• Concrete Blocks or hollow blocks save mortar :Due to uniformity and bigger size saves multi time of quantity of mortar as compared to brick.
• Blocks being  hollow and material used in these concrete or flyash don't enter moisture from External and internal sources, So  these are safe in foundations , load bearing walls& structures . 
• Blocks consume  less quantity of water
• Blocks are light in weight as compared to bricks.
• Hollow cavities in Blocks helps in reducing sound.
• These are available in different sizes according to internal or External applications.
• Flyash used in these Blocks is the by product of coal fires in the  Thermal plants . So these reduce environment   hazard.This is best method to air,water and soil pollution.  

Types of concrete blocks

The concrete blocks are available in different sizes and shapes. The standard sizes of concrete blocks 

• 80cm x 40cm x 10cm 
• 80cm x 20cm x 10cm 
• 40cm x 20cm x 10cm

The concrete blocks have been classified based on their material, usage and typical shapes as below. Solid concrete blocks.

1. Hollow concrete blocks
2. Aerated Autoclaved concrete blocks
3. Concrete bricks
4. Paver blocksL
5. intel blocks
6. Concrete stretcher blocks
7. Corner block
8. Pillar block
9. Jamb block
10. Partition block
11. Frogged brick block
12. Bullnose block

Solid Concrete blocks

The solid blocks used in the construction of the wall where the load occurs. The dead load of the structure will be increased due to the weight of the solid blocks.

The size of the solid blocks can be modified as per our requirement, and You can easily customize these types of blocks near to the site, so it reduces the construction cost.

Normally solid blocks are available in the size of 80cm x 20cm x 20cm, 40cm x 20cm x 20cm and 40cm x 20cm x 10cm.

The masonry method is the same as conventional bricks.

Hollow Concrete blocks

The hollow blocks are mostly used in the construction of high rise buildings. The lightweight concrete is used to mould blocks called hollow blocks.

Aerated Autoclaved Concrete blocks (AAC)

Very thin and lightweight aggregates are used to manufacture the aerated autoclaved blocks. The constituents of cement and aggregates are different compared to the solid blocks. 

The AAC blocks are used in high rise buildings. It reduces the dead load of the structure. So the usage of steel will be reduced at the range of 10% to 15%. The finishing of the AAC block wall gives a smooth finish.
