Abstract
The invention concerns the field of a lightweight building structure produced by using a mortar containing foamed polystyrene and cement and a method for the production thereof. It includes at least one layer of prefabricated foam concrete panel affixed to a reinforcing frame structure wherein interspaces between elements of the reinforcing frame structure are at least partially filled with a mortar providing a first surface contacting the foam concrete panel. The mortar includes granules of 0.5-10 mm size produced by grinding a pressed foamed concrete that has been allowed to mature, 50-200 kg of unbound, anhydrous cement, and 150-300 liters of water added before application per one cubic meter of ground material, respectively.
