The Study of Improvement of Dispersive Soil Using Magnetic Field
In this study, the feasibility of using magnetic technology to reduce the dispersion of soil has been investigated. The reference treatment was potable water and 3 magnetic water devices (with different magnetic intensities) were used for magnetizing the potable water. The results showed that the magnetic field has a significant effect in order of 5 percent on increasing of magnesium concentrat...
متن کاملReducing the Forces Caused by Earthquake on Retaining Walls Using Granulated Rubber-Soil Mixture
In recent years, various studies have been undertaken on how to use waste materials in civil engineering projects. Among waste materials, waste rubber has been highlighted to be used for different purposes such as reinforcing of soil and making of reinforced slopes. To investigate the properties of granulated rubber-soil mixture and its application in making of slopes behind retaining walls, so...
متن کاملPERFORMANCE BASED OPTIMAL SEISMIC DESIGN OF RC SHEAR WALLS INCORPORATING SOIL–STRUCTURE INTERACTION USING CSS ALGORITHM
In this article optimal design of shear walls is performed under seismic loading. For practical aims, a database of special shear walls is created. Special shear walls are used for seismic design optimization employing the charged system search algorithm as an optimizer. Constraints consist of design and performance limitations. Nonlinear behavior of the shear wall is taken into account and per...
متن کاملImprovement Of Thermal Conductivity Of Grout Mixture For Geothermal Heat Pump Systems
A vertical geothermal probe consists of two or four polyethylene tubes U-shaped, used for circulating the coolant between the heat pump and the ground. It is installed in a deep borehole and sealed in a special grout, a kind of liquid cement, used to seal the borehole, and avoid the presence of air bags between the probe and the ground. Moreover, the grout provides a heat transfer medium betwee...
متن کاملComparison of Chemical Grout Properties
Chemical grout use began seriously some thirty years ago with the use of only a few types; silicates, acrylamide, epoxy, and some fatty acid derivates. Since then, the kinds of grout have proliferated with some of the originals still there, others dropping out entirely, and still others changing in type. This paper is about the current uses of chemical grouts, the economics of product use, and ...
