Abstract:
The limestones produced as crushed stone are widely used in the construction sector. Concrete and concrete products are the main materials that need the construction sector. The fact that the natural materials to be used as filling material in the foundations of the building are of high quality is of great importance in terms of building safety. In this study, an industrial structure planned to be constructed in an alluvial soil close to the surface of the groundwater was investigated. The performance of the filler with limestone-based crushed material applied on the foundation was investigated and the properties of the filling material were also determined. It was determined that the limestone used in the filling was 2.56 gr/cm3, the apparent porosity was 0.76 %, the water absorption as 0.37 %, the uniaxial compressive strength was 93 MPa and the point load index was 2.79 MPa. In practice, crushed stone with 3 different grain sizes was used to improve the foundation soil. It is intended to remove the foundation from the capillary area with the 80 cm thick blockage material formed below the foundation level. With the 40 cm thick ballast material laid on the blocking material, it is aimed to reduce the gaps in the blocking material. The top layer of 40 cm thick filler is laid on top and a compressible base bottom surface is formed. The in-situ loading tests provided very high resistance parameters for the filler material. The findings of the study revealed that the success of the application. Copyright © IMCET 2019 International Mining Congress and Exhibition of Turkey. All rights reserved.
