Abstract

The use of waste materials from various factories and industries in the soil to improve engineering properties is one of the new approaches in this field. Inflatable ash is also an important by-product of coal-fired power plants or from the waste heat of some plants, which has a good pozzolanic character and is used in construction projects for use in concrete and in geotechnical projects. Soil stabilization is used. In this study, a type of fly ash with different chemical properties was used in comparison with other studies aimed at improving the existing soil in central Iran. Density, Permeability and CBR tests were performed on samples with different percentages of fly ash with or without lime at different processing times. According to the results of the study, it can be concluded that the addition of fly ash up to 20% in the lime-free Sandy soil will increase the maximum specific gravity dry weight and this amount will decrease to 10% despite the 10% lime content. Find out. The results also show that 20% of fly ash is an optimum value for stabilizing soil with or without lime so that the highest California bearing ratio is achieved in this area. In addition, the use of fly ash has a direct relationship with the reduced Permeability of the specimens. Finally, the results are interpreted on the basis of microscopic photographs of the samples.
