    摘要: Compound intended to be added to concrete mass for entraining air in the concrete, thus increasing frost-resistance of the hardened concrete. The compound consists of: cereal storage proteins from wheat, triticale, barley or rye; a reducing agent preferably in the form of FeSO.sub.4 in an amount adapted to the original properties of the cereal storage proteins to entrain air in the concrete mass during its mixing; an inert substance, preferably Portland cement or mineral powder in an amount adapted to the original capacity of the cereal storage proteins to entrain air in the concrete. By means of the reducing agent and the inert substance the compound is normalized to its effect to entrain air in the concrete irrespective of said original properties and capacity of the cereal storage proteins to entrain air in the concrete. A method to produce the compound includes testing of said properties and capacity in order to adapt the amount of reducing agent and inert substance to the original air entraining effect of the cereal storage proteins used for the respective produced batch of the compound.

    摘要: The present invention relates to the use of blood in the construction and building industry, whereby blood and extracts of blood containing haemoglobin are used as air entraining colloids. The recommended process for preparing a lightened material consists in associating a construction element chosen from the cements, mortars and concretes, with at least one air entraining colloid chosen from whole blood, globules, red blood corpuscles and haemoglobin. The invention also relates to the lightened material obtained according to this process.
