PLASTICITY AND SWELL-SHRINK BEHAVIOUR OF ELECTROKINETICALLY STABILIZED VIRGIN EXPANSIVE SOIL USING CALCIUM HYDROXIDE AND CALCIUM CHLORIDE SOLUTIONS AS CATIONIC FLUIDS
Journal Title: Civil and Environmental Engineering Reports - Year 2019, Vol 1, Issue 29
Abstract
This investigation focussed on the plasticity and swell-shrink behaviour of an expansive soil that was stabilized using electro kinetic stabilization (EKS) techniques with cationic fluids for enhancement of stabilization. 0.25 M solutions of calcium hydroxide and calcium chloride were used as cationic fluids. An electro kinetic (EK) cell of dimensions 500 mm x 150 mm x 160 mm with inert graphite electrodes of size 140 mm x 160 mm x 5 mm was adopted for the stabilization process, carried out at an applied voltage of 40 V over a period of 6 hours. After the duration of the test, stabilized soil sample was subjected to Atterberg limits and free swell tests to determine its plasticity and swell-shrink characteristics. The results of the investigation found that both fluids were capable of reducing the plasticity and swell-shrink behaviour of the soil with different levels of effectiveness.<br/><br/>

RENOVATION AND MODERNIZATION OF HOTEL BUILDINGS - CASE STUDIES IN SILESIA
The cultural heritage of Silesia has different backgrounds and is often characterized by difficult to assess values. There is doubt as to whether some of the existing buildings should be modernized. Since 2000, an increa...
CYLINDRICAL SHELLS MADE OF STAINLESS STEEL – INVESTIGATION OF POSTBUCKLING
The relevant load case of open thin-walled shells is often wind loading during construction. Because of the missing stabilization effect of the roof they show a very high sensitivity to buckling which results into higher...
