Abstract:
The synergy between self-consolidating concrete (SCC) and steel fiber-reinforced concrete (SFRC) technologies may yield, besides the well known and assessed characteristics of each single technology, several interesting peculiar advantages that can be fruitfully exploited by the construction industry, mainly in the field of precast construction. Better controlled fiber dispersion, improved fiber-matrix bond, and enhanced durability due to the higher compactness of the SCC matrix are among the most relevant issues to which the largest part of research efforts were dedicated in the very last decade. The robustness of self-consolidating steel fiber-reinforced concrete (SCSFRC), which relies on sound mix-design methodology and on effective dedicated quality control procedures, has been demonstrated to be crucial in order to achieve the above recalled advantages. This paper summarizes the most significant results of the research activity carried out by the authors in this field, furthermore underlying the outcomes with reference to structural applications.
