Abstract. The paper presents the impact of aggregate contamination on the durability of concrete floors. There were investigated grains impurities which under certain conditions cause damages to the floor surface due to their expansion. On the basis of the analysis of damages recommendations in order to limit such damages were been formulated.

Keywords: concrete floor; durability; swelling aggregates; reactive aggregate.

 

Streszczenie. W artykule omówiono wpływ zanieczyszczeń kruszywa na trwałość posadzek betonowych. Badano zanieczyszczenia ziarnami, które w pewnych warunkach mogą powodować uszkodzenia posadzki spowodowane ich pęcznieniem. Na podstawie analizy uszkodzeń sformułowano zalecenia dotyczące ograniczenia takich uszkodzeń.

Słowa kluczowe: posadzka betonowa; trwałość; kruszywa pęczniejące; kruszywa reaktywne.
