The aim of this study is to obtain the fracture characteristics of low and medium compressive strength self consolidating concrete (SCC) for notched and un-notched plain concrete beams by using work of fracture $G_F$ and size effect model $G_f$ methods and comparing them with those of normal concrete and high performance concrete. The results show that;
with an increase in compressive strength, $G_F$ increases and $G_f$ decreases;
with an increase in depth of beam, the decrease in nominal stress of notched beam is more when compared with that of a notchless beam.
