Abstract

Chemical stabilization is one of the most alternative methods using on soil stabilization with various materials. In recent decades geopolymer has been attention from engineers and experts geotechnical to use it for improvement of soil, because of considered eco-friendly and cost-effective. This paper aims to investigate the influence of used MK-based Geopolymer in geotechnical engineering and to enhance the properties of soil. Where the MK is considered eco-friendly material and cost-effective compared to other materials. Different percentages of Metakaolin-based Geopolymer were used, which are 8, 10, 12, and 14%. It can be concluded that the peak value of strength illustrated when used MK of 10% with curing time 14 days. In addition, Scanning Electron Microscope (SEM) results show the clay particles covered by cementations compounds due to the reaction of the Geopolymer with clay which led to the production of binder particles.
