Influence de la Nature et du Dosage en Fibres sur le Comportement Physicomécanique des Bétons de Sable à Base de Fillers de Laitier Granulé = Influence of Fiber Type and Volume Contents on the Physical and Mechanical Behaviour of Sandcrete with Blast Furnace Slag Fillers

摘要: The objective of this study is to evaluate the effect polypropylene, metal and a mixture two types fiber content, on properties fresh mechanical behavior sandcrete. workability density sandcrete are considerably influenced by nature fibers content. In hardened state, an increase 10 % 30.4% respectively for compressive strength flexural with corrugated steel obtained. On contrary, polypropylene improved slightly resistance. Moreover, 20.5% type's obtained compared reference concrete. Satisfactory results bent elements whose placed only in tensile area. This presents also economical solutions. Key-Words: - granulated slag- metallic fibers- behavior.
