Microstructure 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 کاملOptimizing of Steel Fiber Reinforced Concrete Mix Design
Cementitious matrices are the fragile materials that possess a low tensile strength. The addition of fibers randomly distributed in these matrices improves their resistance to cracking, substantially. However, the incorporation of fibers into a plain concrete disrupts the granular skeleton and quickly causes problems of mixing as a result of the loss of mixture workability that will be translat...
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 کاملCharacterization of fiber distribution in steel fiber reinforced cementitious composites with low water-binder ratio
Image analysis technique is introduced to characterize fiber distribution in steel fiber reinforced cementitious composites. Through cutting and polishing of specimen, image acquisition of specimen surface, extraction of fiber feature, and measurement of related fiber parameters, i.e., dispersion coefficient and orientation factor, are given to quantitatively analyze fiber distribution. Effects...
