Foamed Concrete is an ideal material for tunnel construction and repair. It is used both for the filling of voids created and exposed during tunnelling, and for grouting the finished work, including gaps behind the tunnel lining.
Foamed concrete provides very good material for floor construction. It is ideal for building sub-floors quickly and cheaply and can be used for levelling terrain and raising floor levels as well as for insulation purposes.
The traditional method of making lightweight precast blocks involves the addition of aluminium powder to a wet mortar mix, followed by autoclaving. This is not popular due to the pollution it causes.
Foamed concrete is an environmentally friendly alternative as there are no waste products in its production and all the ingredients are non-hazardous.
