Distribution and Orientation of Fibers in Steel Fiber

Effect of Distribution and Orientation of Steel Fiber

Key-words: Steel fiber, Reinforced concrete, Vibration, Distribution function, Steel orientation . 1 Introduction Fibers are usually used in concrete to control cracking due to both plastic shrinkage and drying shrinkage. If the modulus of elasticity of the fiber is higher than the matrix (concrete or mortar

Checking fiber distribution in steel fiber reinforced concrete

Large ranges of fibers can be used in concrete, steel, glass, carbon, wood, synthetic, natural and more. An optimal design aims to develop a casting process which favors the optimum orientation of fibers in relation to the principal tensile stress distribution. The capacity and ability of electrical resistivity measurement to non-destructively ...

Effects of concrete flow on the distribution and orientation of

To investigate the fiber distribution and orientation within the specimens, the fibers are measured and counted from the 2D X-ray images; this fiber counting process is illustrated in Fig. 8. Before the fiber counting, the X-ray images of each specimen were calibrated using the Image Pro-Plus software [70] .

Assessment of fiber distribution in steel fiber mortar using image

A new test method was introduced to measure fiber distribution in steel fiber reinforced mortar by using image analysis technique. Through specimen preparation, image acquisition, fiber extraction, and measurement of related fiber parameters, quantitative analysis of fiber distribution could be obtained by two parameters, namely dispersion coefficient and orientation factor. Effect of ...

Three‐dimensional modeling of the distribution and

The objective of this study is to propose a new method capable of predicting the variation of the distribution and orientation of steel fibers immersed in the SCC during flow. The flow of the steel fiber reinforced SCC is simulated by a computational fluid dynamics software, in which the volume of fluid method is used to track the free surface ...

Characterization of the orientation profile of steel fiber

The orientation of fibers has a pronounced influence on the tensile behavior of steel fiber reinforced concrete (SFRC) and, consequently, this aspect should be considered in modeling the material constitutive law. Previous works have shown that the tensile strength of SFRC is directly related to the average orientation of the fibers.
