RESISTANCE OF CONCRETE AND PRESTRESSED STEEL TO THE AGGRESSIVE SOIL MEDIUM

THE CAUSES OF (1) CORROSION IN HARD PRESTRESSED STEEL CABLES AND WIRES AND (2) CRACKING, THE PRESENCE OF CAVITIES, HIGH POROSITY OR PERMEABILITY IN THE CONCRETE, CAN BE MINIMIZED BY USING A FORMULA ENSURING CHEMICAL AND PHYSICAL HOMOGENEITY OF THE CONCRETE AND BY CARE DURING ITS LAYING. THIS SHOULD BE COMPLEMENTED BY A THOROUGH STUDY OF THE SOIL IN WHICH THE CONCRETE STRUCTURE IS TO BE PLACED. THE ABSOLUTE AGGRESSIVENESS OF SOIL AS REGARDS CONCRETE PIPES CAN BE DEFINED BY A LOW ELECTRIC RESISTIVITY DETERMINED BY ANALYZING CHLORINE, SULPHATE AND CARBONATE IONS BY ITS PH VALUE AND BY ITS PERMEABILITY. THE RESISTIVITY LIMIT OF CONCRETE PIPES TO THE AGGRESSIVENESS OF THE SOIL DEPENDS ON THE COMPACTION OF CONCRETE. /RRL/
