In this study, the following conclusion was derived from the evaluation of the engineering nature of CLSM using a large amount of CA. First, the result was confirmed that it is effective in ensuring a flow for field application if the unit quantity is set to 370 to 385 (kg/m3) and the AE agent is mixed to 0.3~0.35 (kg/m3), when the c/a ratio is set to 35% or more. Second, when the ratio of c/a is set to 35% or more, it was confirmed that the AE agent is mixed to be effective in suppressing the bleeding rate if the unit quantity is set to 385 (kg/m3) or less. Third, CLSM with 30% and 35% c/a ratios set, respectively, showed the most intensity motion for field application. Fourth, it was confirmed that a fine amount below the acceptable standard was detected for heavy metal ions such as As, Pb, Cd, and Se other than Cr, resulting in no effect on the surrounding environment by the use of CA.
