Durable Glass Fiber Reinforced Concrete with Supplimentary Cementitious Materials
Durability of concrete structure in marine environments is a big issue for many decades due to chloride attack. Chloride penetrates the concrete structure and accelerates the corrosion process of reinforcement which decreases the life of those structures. Also shrinkage cracks in concrete play main role for chloride penetration through concrete surface. Many researchers tried to find easy and ...
متن کاملEffect of surface treatments on damping behavior of carbon and glass fiber reinforced friction material
The ability to absorb vibrations in a vehicle during braking conditions depends primarily on the selection of ingredients for a friction material and interfacial adhesion between all these ingredients. In this work, a hybrid brake friction material is developed by combination of carbon fiber (CF), glass fiber (GF), resin and other ingredients. The surfaces of carbon and glass fibers are c...
متن کاملPolyvinyl Alcohol Fiber Reinforced Engineered Cementitious Composites: Material Design and Performances
Polyvinyl alcohol (PVA) fiber is considered as one of the most suitable polymeric fibers to be used as the reinforcement of engineered cementitious composites (ECC), though the unique microstructure characteristics of PVA fiber add challenge to the material design. In this paper, the micromechanics based design procedure for a PVA-ECC suitable for structural applications is described, and pract...
متن کاملHigh Performance Fiber Reinforced Cementitious Composites as Durable Material for Concrete Structure Repair
This paper addresses the property requirements of repair materials for high durability performance for concrete structure repair. It is proposed that the high tensile strain capacity of High Performance Fiber Reinforced Cementitious Composites (HPFRCC) makes such materials particularly suitable for repair applications, provided that the fresh properties are also adaptable to those required in p...
متن کاملFlexure Toughness of Polymer Fiber-reinforced Cementitious Materials
In this article, the toughening effect of polymer fibers in cementitious materials is analyzed through an energy method. When a crack front encounters a fiber array, additional fracture work is required to overcome the barrier effect. The influences of fibers, matrix, and crack length on the critical energy release rate are collectively described by a single system parameter.
