Treść
Waste aggregate concretes are playing a more and more important role in construc-tion industry. Over the last decade, their application has evolved from very basicpavements and elements with limited mechanical characteristics to full scale struc-tures and large pre-cast beams and slabs. In some cases, steel fiber was used as theonly reinforcement of such elements. The application of steel fiber was based onthe assumption that the influence of dispersed reinforcement would be the same asit was in ordinary concrete. Therefore, both technologies of preparation of suchconcrete and volumes of added fiber were the same as in ordinary concrete. Inauthors’opinion, concrete based on waste aggregate creates much more complexenvironment for fiber reinforcement than traditional cement matrix. Recognizingthe need of comprehensive approach to this problem, authors conducted a thoroughresearch program. Concrete based on waste red ceramic aggregate was modified bydifferent volumes of varied engineered steel fiber. Conducted tests covered fullmechanical characteristics. Strength classes according tofibmodel code wereassigned to tested fiber concretes. The best mixes were pointed out.
