Interaction Effect of Usage of Polypropylene Fiber and Zeolite on Strength Parameters of Silty Sand

Interaction Effect of Usage of Polypropylene Fiber and Zeolite on Strength Parameters of Silty Sand

Due to the increasing cost of high quality materials needed for different geotechnical projects, engineers try to improve the physical properties of local soils through- out different methods and techniques. This paper investigates interaction effect of usage of polypropylene fiber and zeolite on strength parameters of silty sand. Accordingly, usage of an additive material besides fiber, raises an issue about synergistic interaction effect on soil strength. Usage of fiber or zeolite lonely is ...

Investigating the Effect of Applying Polypropylene Fiber on Compressive Strength of Self-consolidating Concrete

Investigating the Effect of Applying Polypropylene Fiber on Compressive Strength of Self-consolidating Concrete

Mechanical characteristics of fiber concrete is affected by type, percentage, length to diameter ration, context resistance, size and shape of fiber, sample preparing method and size and shape of sand material. Therefore, in order to use in each case, mix design should be prepared and it must be tested. The current research have been designed and conducted in order to examine the effect of applying propylene fiber on pressure behavior of Self- consolidating concrete. Washed sand with fineness ...

Voltage Effect on the Optical Properties of Liquid Photonic Crystal Fiber

Voltage Effect on the Optical Properties of Liquid Photonic Crystal Fiber

The parametric performance of the photonic crystal fiber (PCF) infiltrated by LC 5CB is studied under the voltage variations. The COMSOL and MATLAB softwares have been used to study the performance of PCF under the variations of optical parameters including the effective refractive index, the normalized frequency, the effective mode area, numerical aperture and waveguide dispersion. Results indicated that both single-mode transmission and ultra-flat dispersion can be achieved under the ...
