Abstract:
Draws attention to some early papers by both the Mathers of particular and lasting significance. Three factors relevant to so many current problems with durability of concrete are reviewed: first, inadequate criteria for acceptance of concrete, strength alone being relied upon in the past; second, changes in cement properties over the years, which allowed the use of leaner mixes for a given specified strength; and third, the corrosion of steel in the concretes used nowadays, particularly severe in hot climates. Finally, recommendations are made for more attention to the composition of the mix and for inspection and maintenance of concrete structures.
