Abstract: 
The present paper presents a systematic evaluation of cracking sensitivity, addressing the major parameters in concrete technology, especially for the high end of concrete quality. The variables studied were w/c ratio in the range of 0.29 to 0.45, cement content, type of cement (CEM I, CEMII and CEMIII), and the type of mineral additive added to the concrete (fly ash, metakaolin and microsilica). The performance of the concretes was evaluated by determining free shrinkage and weight loss upon drying, development of compressive strength, and characterization of cracking using the ASTM C 1581 ring test. Classification of the various parameters with regards to cracking sensitivity was performed based on the ASTM criteria and also on a more advanced one which was developed by the authors. The influence of the various variables was discussed in terms of the development of the whole array of the basic properties.
