Determination of engineering properties of high plasticity clays stabilized with sodium silicate

The necessity of accommodation has been one of the most important requirements of humanity immediately after its emergence. The inevitability of this necessity has enabled some professional groups to develop over time. With the technological activities that have developed in the following times, human beings have enabled the rapid development of the construction sector and the addition of new features. There are many engineering services in the construction sector. Some of them are geophysical engineering, civil engineering and geotechnical engineering. Along with the developing technological events, innovations have emerged in all engineering services and continue to emerge. Innovations in geotechnical engineering show that different methods have been used to improve the soil properties. It is extremely important to investigate how the soil is characterized and how the problems we encounter on the investigated ground should be solved. Investigating the fact that the soil has bad properties and how these bad properties should be improved, has tried to prevent construction activities from being carried out in different places. Clay, one of the floor types, can be found in almost every area of the world. If high swelling/shrinkage potantial and other important problems are taken into consideration, the importance of the studies to be carried out in this area in addition to improving clay soils has increased. In construction activities, soil improvement methods are used to eliminate problems such as swelling/shrinkage of clay soils. There are many studies conducted on clay soils, and the vast majority of them are related to stabilization. Stabilization of clays is also a soil improvement technique. Stabilization is generally divided into 3 groups. These are chemical, mechanical and injection. Hydrometer, sieve analysis and atterberg limit determination experiments performed on the ground are the experiments that were performed at the beginning of this study. With the result obtained from these experiments, it has been understood that the samples have high plasticity. After this result, proctor tests were performed by adding sodium silicate into the samples. Free pressure experiments were carried out with samples with a high plasticity clay and sodium silicate mixture prepared in an optimal water content and in an optimal wet content. The samples made in optimum and optimum wet condition were kept under two different curing conditions (open environment, wrapped in stretch). It has reduced the strength values of the clay soil with sodium silicate. Since the strength values of the sample decreased with the increase in the sodium silicate ratio, it has been found that there is an inverse ratio between the two. Studies have shown that sodium silicate is not an effective stabilizer for the improvement of high-plasticity clay floors.
