CHARACTERISTICS OF THE ATTACK OF CEMENT PASTE BY MGS04 AND MGCL2 FROM THE PORE STRUCTURE MEASUREMENTS

This paper deals with the attack of cement paste by magnesium sulphate and magnesium chloride solutions. The analysis of the pore structure using mercury porosimetry reveals distinct characteristics of both types of corrosion. Magnesium sulphate is associated with the densification of the pore structure, whereas magnesium chloridee corrosion is associated with the opening of the pore structure. Mineral additives seem to protect somewhat 14d-cured cement paste against the magnesium sulphate attack. A longer initial cure is necessary as far as magnesium chloride attack is concerned.
