The article presents novelty aspects for the modern approaches proposed in reviewing the European standard EN 206 „Concrete - Specification, performance, production and conformity” regarding concrete’s equivalent performance concept and the theoretic basis for the experimental determination of “k” coefficient in case of using additions in concretes in order to obtain performances equivalent to those of concretes without additions.  In the article are presented theoretical application methods and/or experimental applications of such methods performed by the authors. The methods, suggested in the European standard, will be the basis for Romanian regulations’ review regarding the production of concrete.
