Abstract

The foundation of any structure and construction of roads are most affected by different problems when it is constructed on weak soil such as organic soil for example. The use of recycled glass powder as a precursor in geopolymers improves soil properties (enhancing bearing capacity and reducing compressibility), as well as prevents glass waste from accumulating in landfills. The recycled glass powder (RGP) was added to the soil with different percentages(5,10,15,20 and 25)%. Sodium hydroxide (NaOH) is used as an alkaline solution. The chemical composition of RGP and the organic soil are determined by the X-ray fluorescence (XRF) test. Unconfined compressive strength (UCS) was conducted to investigate the mechanical behavior of specimens. The results show that increase in UCS in 7 and 14 days for the specimens treated with geopolymer compared to the natural soil specimens. The highest UCS value was 7,86 MPa at a curing time of 14 days and a curing temperature of 65C with 20 % RGP
