High-strength Concrete with Natural Aggregates, Silica Fume, and Polypropylene Macrofibers
The use of concrete with polypropylene macrofibers can reduce the fragility and shrinkage of silica fume mixtures.Here, we investigated the effect silica fumes and aggregates have on enhancing high-performance concrete with polypropylene macrofibers.Three dosages of polypropylene macrofibers were evaluated (0.39, 0.63, and 0.79 % volume fraction),
