The effect of Application of Polypropylene and Zeolite in Correction of Strength Parameters of Silty Sand

The effect of Application of Polypropylene and Zeolite in Correction of Strength Parameters of Silty Sand

Achievement to conditions with more economic efficiency has been of the main objectives of construction projects, so that reinforcement of bed soil in these projects can be effective in obtaining of those objective. In order to realize those objectives, wide studies have been conducted which resulted in very various methods of improvement (physical, mechanical, and chemical). In this way, due to efficacy and special capabilities of mechanical methods, using of Polypropylene fibers have drawn ...

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 ...

Compare the physical parameters of the single diode organic solar cells with two diodes

Compare the physical parameters of the single diode organic solar cells with two diodes

In this solar panel design parameters, using the Lambert function has been studied. With this function by using the experimental results, we investigated the effect of shadows And found that there is a shadow on a cell reduces the open circuit voltage and short circuit current increases. Interest and also reduces congestion and increases the saturation current of the first diode and the first diode parallel resistanceAnd the second diode is ideal factor And photo-current generated in the cell ...
