Abstract: The results of standard restrained shrinkage ring tests demonstrate that introduction of supplementary cementitious materials (SCM) in concrete mixes and reduction of clinker content in the cement do not necessarily reduce the cracking potential. These results are contradictory with findings of other authors demonstrating that binary and ternary cementitious binders, in spite of their higher autogenous shrinkage potential, often exhibit later autogenous cracking ages than the control Portland cement mix. The reasons of this contradiction are hereby analysed.
