AAC Technology

Building with AAC (Autoclaved Aerated Concrete) Factory manufactured Components
AAC is factory made with fine silica (sand), cement, lime, water and an aluminum powder (as
the expansion agent that causes the mixture to rise until it contains 80% air). It is baked for
about 8 hours, then cut into precisely dimensioned units of panels, blocks lintels etc. Cured
units are joined with thin bed mortar and can be used for walls, floors and roofs.The lightweight
material offers excellent sound and thermal insulation, is strong and fire resistant. In order to be
durable vis-a-vis the weather, AAC – being porous – requires some type of applied finish, such
as a polymer-modified stucco, stone or other siding.
AAC combines insulation and structural capability in one material for walls, floors and roofs.
The light weight/cellular properties make it easy to cut and shape, accept nails and screws and
allows it to be routed for electrical and plumbing conduits. Adjustments are easily made. As the
AAC product is non-combustible, it will neither burn nor give off toxic fumes.

Moving forward with AAC:

Having identified the AAC home building construction technology as most appropriate for the future building of homes in Western Canada – subsequent to the disastrous forest
fires in BC, Alberta, Saskatchewan and Manitoba during the past few years, and last year’s BC
flood, – the time has come for taking action. The procedure would be to initially import and
instal AAC blocks, panels and lintels, to be followed by a feasibility study for the construction
of an AAC manufacturing plant.
