Acoustic Emission Activity in Ductile Fiber Reinforced Cementitious Composites
This study was performed in the framework of a research program focused in the development of high tenacity polypropylene (PP) fibres for the reinforcement of cementitious composites. Precedent reports have demonstrated how micromechanical modelling was used to attain significant improvements with respect to the macroscopic properties of cementitious composites. These improvements have been bas...
متن کاملStudy on Impact Resistance of Pc Beams with Buffer Layer Made of Ductile Fiber Reinforced Cementitious Composites
In concrete structures such as road facilities, harbor facilities, sediment control dams, and others, impact loads sometimes act directly on members. Load bearing capacity, toughness and displacement recovery properties are important, and should be evaluated appropriately. Recently, to prevent the spalling of concrete portions is also one of the important requirements for concrete structures. T...
متن کاملMonotonic and fatigue performance in bending of fiber-reinforced engineered cementitious composite in overlay system
This paper presents an experimental study and theoretical analyses on the monotonic and fatigue performance in bending of a polyvinyl alcohol (PVA) fiber-reinforced engineered cementitious composite (ECC) overlay system. The influence of the interfacial characteristics between overlay and old concrete substrate on the overall bending performance is investigated. The experimental results show th...
متن کاملMicrostructure variability and macroscopic composite properties of high performance fiber reinforced cementitious composites
High performance fiber reinforced cementitious composites have made major advances in recent years, to the point where they are being adopted in building and bridge constructions. The most significant advantage of HPFRCC over conventional concrete is their high tensile ductility. However, the tensile strain capacity has been observed to vary, most likely as a result of the variability of the mi...
متن کاملRetrofitting of Reinforced Concrete Beams with Steel Fiber Reinforced Composite Jackets
In the present study, a new method for retrofitting reinforced concrete beam is introduced in which steel-concrete composite jackets containing steel fiber is used. For this purpose, 75% of the peripheral surface of reinforced concrete beams was initially reinforced using steel plates and bolts, and steel fiber reinforced concrete was used between the steel plates and the peripheral surfaces of...
