A manufacturing technique of high quality stabilized dredging soil is newly presented in this study. In the technique, a simple drumstyle mixer without power-driven machinery is used at the process of mixing dredging soil with cement through a compressed-airmixture pipeline in order to improve the mixing of two materials. The prototype tests for the producing of stabilized dredging soil are conducted in the cases with and without the drumstyle mixer, and it is found that the strength of the stabilized dredging soil using this new technique becomes greater comparing with the case using the previous technique without the mixer under the same transporting distance of two materials. The systematic tests are also conducted with different mixer's height h and diameter d, for the discussions about the optimal mixer's shape. Furthermore, the practicalness of this technique is discussed through the test producing the amount of stabilized dredging soil per hour that is needed under actual construction of reclamation.
