Los Castros s/n, Santander 39005, Spain h i g h l i g h t s g r a p h i c a l a b s t r a c t Fatigue behavior of recycled concrete have been analyzed. A total of 24 mixtures were studied. The fatigue limit has been obtained by the Staircase method. The loss of fatigue limit is greater for lower water/cement ratios. a r t i c l e i n f o a b s t r a c t Article history: This paper presents the main results of the research carried out to obtain the fatigue limit of concrete Received 10 April 2013 incorporating recycled aggregate from concrete.
