freezing and thawing which in turn can lead to potential spalling in concrete. Water naturally freezes and expands in the cold, and this can be highly damaging to many variants of concrete. Due to the density of the blocks, aircrete possesses enhanced freeze/thaw durability, giving it a lower chance of being damaged during the colder months. These performance characteristics have been tested and certified by the BBA.
Resistence to sulphates
Sulphate attack is another potential danger for foundations. It can cause damage serious enough to compromise the structure of a home. This occurs when natural sulphate in clay soils leaches into the foundation materials, causing certain types of materials to expand. Certain types of concrete material are highly susceptible to attack from sulphate chemicals that exist in soil and groundwater. Unlike the concrete equivalent, aircrete
blocks have been shown to have superior resistance to sulfate attack when used below DPC. Aircrete has been tested and assessed by the BBA as being suitable for use across all applications where sulfate level are likely to be encountered. Aircrete blocks possess a number of advantages over traditional materials, which
“Aircrete is fully load-bearing and blocks are available in a range of strengths up to 8.7N/mm2, in buildings up to three storeys”
make them a fantastic all-round material for use below DPC level. By making a simple material switch, housebuilders can enjoy improved logistics and performance benefits,
which is more than enough for use
while also saving money on construction costs. When all the facts are considered, all directions point towards aircrete being the foundation material of the future.
