100mm Celcon H+H Standard Grade Plain Face 3.6N Block
Celcon blocks are a type of concrete masonry unit made of a mixture of sand, pulverised fuel ash (PFA), cement, lime and water. These components are blended into a slurry, with a small quantity of aluminium powder added to the mixture - the result is a strong and lightweight building material.
For the sake of eradicating on-site confusion, Celcon aircrete blocks can be utilised in all manner of applications, namely in floor and wall applications - solid or cavity walls.
With their exceptional thermal, acoustic, and load-bearing capabilities, Celcon blocks offer practical solutions that meet current Building Regulations, as well as being well-equipped to meet the Future Homes Standard, set to be implemented in 2025.

Frequently Asked Celcon Blocks Questions
What Does Aircrete Mean?
Aircrete is one of the lightest forms of concrete with exceptional structural, thermal, sound, fire, and freeze/thaw properties.
It has been used in the UK since the 1950s and is made of pulverised fuel ash (PFA), sand, cement, aluminium powder, lime, and water.
What Are Mortar Perpends/Perps?
The term "perpends" comes from old English and refers to the head or vertical mortar joints in bricks. Unlike horizontal bed joints, which are easier to fill, head joints require proper butting to prevent gaps in the wall system.
What Makes AAC Block wall Masonry More Cost-effective Than Brick Wall Masonry?
The standard AAC block is 9 times larger than traditional brick, resulting in fewer joints and reducing the amount of cement needed.
AAC blocks are factory-made, providing a smoother finish and more precise specifications. Additionally, the larger size and lighter weight of AAC blocks make transportation and construction faster, while also reducing labour costs.
