Application of Flyash in Building Ground Treatment

A project example in which flyash is used in ground treatment is introduced.The optimum mixture ratio of lime-flyash-soil cushion is determined through the analysis of physical and mechanical properties of lime-flyash-soil samples with different mixture ratios. Field compaction test is done under the optimum mixture ratio.Field bearing tests show that this treatment method is successful.Lime-flyash-soil cushion is prominently economical and worth popularizing.
