Development of Autoclaved Aerated Concrete (AAC) began in early 1920’s in Sweden and Architect, Johan Eriksson, patented the manufacturing process in 1924.
Production was licensed in 1928 and the first manufacturing facility built in 1929.
It took until 1988 AAC for the first production plants to be built in Egypt and our product is now known as DELTA BLOCK.
This workability and easy to use, makes Delta Block an unparalleled product to work with.
A German study concluded that Delta Block outlasts all other wall materials and in addition showed after 80 years strengthening improvement.
The highest fire resistance factor at all Light Weight Blocks are noncombustible Fire resistance Rating 2hr at 1200 ْc.
The specific characteristics of Delta Block allows the material to deform under tensile stress and hence cope with the movements of a seismic activity.
As seen in the picture, the house made of Delta Block (AAC) survived virtually intact from the KOBE earthquake.
