Soil improvement with waste pvc

Abstract

Due to the increase in the population, the lands where safe constructions can be done have decreased. Therefore, there is a need to construct to grounds with low bearing capacity. Accordingly, improving the soil in geotechnical engineering is becoming more and more important day by day. Soil improvement is making the soil with insufficient strength resistant to external loads by mechanical, physical, or chemical improvement methods. There are many studies in the literature on soil improvement related to fly ash, furnace slag, recycled rubber aggregates, waste glass pieces, waste brick and marble pieces, chemical additives, polymer materials, geotextile materials. In this study, 0th and 28th days samples were prepared by adding 5%, 10%, and 15% waste PVC fibers to a cemented clay soil obtained by adding 10% cement. The prepared samples were subjected to the uniaxial pressure test, and it was observed that the waste PVC fiber affected the free compressive strength of the cemented clay soil. © 2020, TUBITAK.
