Experimental Study of the Geotechnical Behavior of Calcareous Soil Improved using Kaolinite Clay - a Comparative Study
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 2
Abstract
The calcareous soil is commonly composed of calcium carbonates greater than ten percent. Generally, the calcareous soils are extensively found near the coastal areas of Egypt. Accordingly, the performance of calcareous soils is usually connected with different interdependent problems, such as crushability, compressibility, and chemical dissolving. Thus, the main goal of the present study is to explore the feasibility of applying a treatment approach in the improvement of calcareous soils toward mixing the calcareous soil with Kaolinite clay. Moreover, investigating the effect of different types of water (e.g. fresh and seawater) used in compacting the treated calcareous soil on its performance. The results have shown that the addition of Kaolinite up to 9% to the mixtures significantly decreased the optimum water content but increased the maximum dry density. Wherein, both of the decrease ratio in optimum water content and the increase ratio in maximum dry density became more significant in the state of seawater. The California bearing ratio “CBR” values of the Kaolinite – carbonate mixtures increased with the addition of Kaolinite up to nine percent. However, it is lowered when it soaked in fresh water for three months.
