Abstract

Method for manufacturing cement paste, which expands and flows freely, with low water content, characterized in that it comprises: grinding cement clinker to a specific surface area of between 6,000-90000 cm2/g and mixing the ground cement with at least minus 0.0025 parts by weight of alkaline, alkaline earth or ammonium lignosulfonate and then with approximately 0.2 parts by weight of water containing at least 0.0025 parts by weight of alkaline or ammonium carbonate, all per part of cement ground.
