PORE STRUCTURE

MOST OF THE IMPORTANT PROPERTIES OF HARDENED CONCRETE ARE RELATED TO THE QUANTITY AND CHARACTERISTICS OF THE VARIOUS TYPES OF PORES IN PASTE AND AGGREGATE COMPONENTS OF CONCRETE. THE PAPER DISCUSSES THE POROSITY OF CONCRETE, CAPILLARY AND GEL PORES IN CEMENT-WATER PASTES, AGGREGATE PORES, AIR VOIDS, PERMEABILITY AND ABSORPTION OF CONCRETE, FREEZING PRESSURE, OSMOTIC PRESSURE, AND EFFECTIVE PORE AREAS. /PCA/
