Abstract

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; (i) with an increase in compressive strength, G F increases and G f decreases; (ii) 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.
