Concrete samples
Germany
DE 1, Drill core sample from a sandwich wall element with thermal insulation (polystyrene) 5 cm thick and weather shell designed as exposed aggregate concrete. Base layer of ~16 cm reinforced concrete missing.
DE 2, Verification of the corrosion-proof embedding of the reinforcement using phenolphthalein (pH indicator); purple tint = non-carbonated area ; Concrete cover over rebars ~5 cm (non load-bearing weatherproof shell)
