DURABILITY OF CONCRETE--FIFTY YEARS OF PROGRESS?. IN: DURABILITY OF CONCRETE. SECOND INTERNATIONAL CONFERENCE. AUGUST 4-9, 1991, MONTREAL, CANADA. VOLUME I

This paper reviews the proceedings of the cement chemistry congresses as well as other symposia held during the last 50 years by ACI, ASTM, and RILEM. What is presented is a state-of-the-art report from the author's perspective. In order of decreasing importance, the major causes of concrete deterioration today are: corrosion of reinforcing steel, frost action in cold climates, and physico-chemical effects in aggressive environments. There is a general agreement that the permeability of concrete, rather than normal variations in the composition of portland cement, is the key to all durability problems. A rise in chemical aggressivity of the environment through the increasing use of de-icer salts, and an increase in land, water, and air pollution, has also contributed to concrete durability problems.
