CONCRETE MICROSTRUCTURE AND ITS RELATIONSHIPS TO PORE STRUCTURE, PERMEABILITY, AND GENERAL DURABILITY. DURABILITY OF CONCRETE. G.M. IDORN INTERNATIONAL SYMPOSIUM, 1990 ANNUAL ACI CONVENTION, TORONTO, ONTARIO, CANADA

The principal mechanism for the deterioration of concrete is transport of fluids either into or out of the pore structure of hardened body. The fluid transport occurs via a complex network of interconnected porosity incorporating both the comentitious matrix and matrix/aggregate interfacial regions. This paper describes the development of an experimental method and a mathematical background for a rapid water permeability measurement method and a mathematical model relating porosity, described in terms of a log-normal distribution, to permeability.
