Abstract: Plastic shrinkage cracking can become problematic especially in concrete elements with high surface to volume ratio such as slabs and pavements. In this paper two test methods commonly used when studying the phenomenon have been evaluated; ring test method (NORDTEST-method NT Build 433) developed in NTNU/SINTEF by Johansen and Dahl in order to study the effect of different materials and constituents on the cracking tendency at macro-level, and ASTM C 1579, mainly designed in order to map the influence of fibres. During this research, influence of coarse aggregate content on plastic shrinkage cracking of self-compacting concrete (SCC) was studied. Preliminary results show same tendencies with the two methods i.e. a lower plastic shrinkage tendency with higher amount of coarse aggregates.
