PROPERTIES AND BEHAVIOUR OF CONCRETE AFTER 29 YEARS OF SERVICE

EIGENSCHAFTEN UND VERHALTEN VON BETON NACH 29 JAEHRIGER LAGERUNG

Numerous slabs 70 x 40 x 15 cm made of very different types of concrete were in service for 29 years, are lower halves being in very soft, flowing water. The surfaces which had been exposed to weather had only lost about 3 mm of lime mortar, in the worst cases, and the surfaces which had been underwater had lost about 7 mm. There was practically no rusting of the reinforcing bars, which had been covered with 30 mm of concrete, and the compressive strength had increased in all cases, sometimes considerably.
