Fig. 1 Aerial view of Baixo Sabor dam after the first filling of the reservoir 2.3. DAM CONCRETE The dam has a total concrete volume of, approximately, 670,000 m3. The 32 blocks were cast in 2.0 m height layers. The placement of concrete began in 2011 and ended in 2013. The cementitious materials were Portland cement CEM I 42.5R and a class F fly ash. The fine and the coarse aggregates were granitic, obtained by crushing the rock from a quarry located on the right bank of the river, upstream. The concrete mixtures presented in Table 1 correspond to the concretes most used in the dam.
