Results showed that the optimal geopolymer combination ratios from the viewpoint of bearing the maximum compression, was obtained composed of 15% glass powder, 7% calcium carbide, and 25% silt, and concentrations of higher/lower of the optimum value, will be reduced the compressive strength. Dynamic shear modulus of soil-geopolymer was higher than soil-cement, while it was the reverse in terms of damping ratio. Shear strength, stiffness and damping ratio of the soils with various fines content increases up to fines threshold (50% silt). optimal values of soil static and dynamic properties were found in 25% and 50% silt, respectively. %U https://ceej.aut.ac.ir/article_4928_6829d17ec16c21b134ddaf94cc2654e4.pdf
