The project titled "Investigation of the Performance of the Pile Raft System Produced Using Recycled Concrete Aggregate Geopolymer Under Vertical and Lateral Loading" by Prof. Dr. Murat Olgun, Faculty of Engineering and Natural Sciences, Department of Civil Engineering, was deemed worthy of support within the scope of TÜBİTAK 1001-Scientific and Technological Research Projects Support Program.
The project aims to expand the use of recycled materials in Geotechnical Engineering applications and to replace the use of natural materials, to prevent CO2 emissions caused by cement production and to prevent environmental pollution caused by the storage of concrete in landfills and to put forward an environmentally friendly and economical approach. The project is especially valuable in utilizing construction demolition waste generated during urban transformation processes and stored in stockpiles, or waste generated in unexpected sudden situations such as the recent Kahramanmaraş earthquakes.
Within the scope of the project, it is planned to use recycled concrete aggregate (GDBA) obtained especially from urban recycling wastes as aggregate, and geopolymer binder formed by using fly ash, silica fume and blast furnace slag raw materials from industrial waste materials as precursor material (PM) in composite form. In the study, the compressive and flexural strengths of the geopolymer mortar with GDBA and its durability against harmful environmental effects (sulfate water and salt water) are among the subjects to be investigated. The optimized geopolymer composite material will be used in the creation of pile foundations, which are one of the important applications of Geotechnical Engineering. Pile foundations under the structure are generally designed as pile-raft foundations, especially for the solution of settlement problems. Within the scope of the project, the stress-deformation behavior of pile-raft foundations produced using geopolymer with GDBA under the effect of vertical and lateral loads will be investigated with high quality instrumental measurement devices, and the load sharing ratios and stress distributions occurring in the soil in pile-raft foundations will be analyzed experimentally and numerically.
Prof. Dr. Murat Olgun will be the advisor of the project to be carried out by Prof. Dr. Ülkü Sultan Keskin from the Department of Civil Engineering, while the project researchers will be Prof. Dr. İbrahim Hakkı Erkan from the Department of Civil Engineering, Dr. Lecturer.
