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

Underwater structures represent a significant portion of concrete works worldwide. The utilization of various underwater concrete techniques has indeed minimized the use of costly dewatering processes. Such techniques include the use of special· equipment such as trernie concrete and preplaced aggregate technique. The incorporation of antiwashout admixtures has evolved as a method to minimize the washout of cement and fine particles. As for today, there exists relatively limited information regarding different underwater concreting techniques to facilitate feasible and adequate selection of appropriate methods. This work comprises a survey study and an experimental work to evaluate the impact of using the …
