Description
  • Durability belongs to the most important concrete parameters. In case of cement-concrete wearing courses of roadways, we are speaking about concrete surface resistance to impact of frost and thawing alternation and to impact of applied defrosting chemicals. Owing to newly built cement-concrete roadway wearing courses, this parameter has been detected on 28th day after the concreting. For subsequent repairs, however, we cannot eliminate a situation, in which the built in concrete showing the strength parameters typical for the age of 1 or 3 days will be exposed to frost and to impact of defrosting chemicals during a period of less than 28 days. In repairs of cement-concrete wearing courses, concretes using gypsum free cements and representing the high performance types also are applicable.

  • Jedním z důležitých parametrů betonů je jejich trvanlivost. U betonů pro cementobetonové kryty vozovek se jedná o odolnost povrchu betonu proti účinkům mrazu, tání a rozmrazovacích látek. Tento parametr je u nově budovaných cementobetonových krytů zjišťován ve stáří betonu 28 dní od jejich vybetonování. Při provádění oprav nelze však vyloučit stav, kdy zabudovaný beton, který dosahuje požadovaných pevností ve stáří 1 až 3 dny, bude vystaven účinkům mrazu a rozmrazovacích látek v době kratší než je 28 dní. Pro opravy cementobetonových krytů lze používat i betony s bezsádrovcovými cementy, které jsou jedním z typů vysokohodnotných betonů. (cs)
