Interaction Of Silica Fume And Polypropylene Fibers In High Performance Concrete, May Tarek Massoud

Archived Theses and Dissertations

The use of mineral admixtures and fibers is becoming essential in the new generation of high performance concrete since they introduce enhancement in mechanical properties as well as several durability aspects. Some of the advantages gained when properly employing high performance concrete are significant improvements in strength, drastically reduced permeability, better resistance to a wide spectrum of chemicals, superior performance in freezing and thawing conditions and enhanced thermal resistance. Although silica fume and polypropylene fibers are increasingly used in high performance concrete, yet, relatively little work has focused on the interaction of both ingredients in such concretes. The main aim …
