Introduction of Concrete Block

Concrete blocks typically have holes, which makes them lighter and easier to handle. In the vertical direction, i.e., in line with the axis of the holes, they are very strong. They are used for foundation walls, which may be subjected to very heavy loads. A concrete block is primarily used as a building material in the construction of walls. It is also called a concrete masonry unit. A concrete block is one of several precast concrete products used in construction.
Concert Blocks are lightweight generally it is used in high rise building to reduce structural load. Concrete blocks are easy to handle compare to red clay bricks; they are larger in dimension and superior in quality and most importantly save in time and cost. Concert blocks are easy to cut as the concert block surfaces are very smooth wall putty can be directly applying on the surface of the inner wall of the house to give it the perfect finish before painting.
Introduction of Fly Ash Bricks

Fly ash brick is lightweight, but still has good strength in compression. It is not used for walls that are subjected to the greatest loads, such as foundation walls or interior load-bearing walls. It is suitable for light-duty applications.
Fly ash bricks are a building material, specifically masonry units, containing class C or class F fly ash and water. Compressed at 28 MPa and cured for 24 hours in a 66 °C steam bath, then toughened with an air-entrainment agent, the bricks last for more than 100 freeze-thaw cycles.

While comparing concrete blocks vs fly ash bricks, there arises confusion in selection of masonry units for constructing a house. Here we have given comparison between Concrete blocks, fly ash bricks, to help you make the right choice.

1. General
Concrete blocks have one or more large holes or cavities which either pass through the block (open cavity) or do not effectively pass through the block (closed cavity). They have the solid material between 50 and 75 % of the total volume of the block calculated from the overall dimensions. 
Fly ash bricks are eco-friendly bricks which are made using fly ash or pulverized fuel ash. They are also called pulverised fuel ash – lime bricks. They are 100% solid and they do not have any cavity unlike Concrete Blocks.

2. Raw Material
Concrete blocks consist of a mixture of cement, aggregates, sand or gravel and water. Sometimes industrial waste like fly ash, bottom ash etc. are also used in their manufacturing.
Fly ash bricks are made from the mixture of fly ash or pulverized fuel ash, cement, sand, lime and gypsum.

a. Exterior load-bearing walls

c. Curtain walls
d. Partition wall and panel walls
e. Backing to stone, brick, and other facing
f. Fireproofing over a structural member
g. Fire-safe walls around elevators and stairwells
h. Piers, retaining walls, column etc.

a. Raising Infrastructures
b. Factories
c. Warehouse
d. Power plant
e. High rise structures etc.
f. Construction of pavements

h. Canal lining
i. Irrigation work

4. Water Absorption
Water absorption of concrete blocks should not exceed10% of its weight.
Water absorption of fly ash bricks should not exceed15-20% of its weight. Thus, its normal water absorption is higher.

5. Cost
