CONSIDERATION FOR PRODUCTING HIGH STRENGTH SOLIDIFIED SOIL BLOCK BY MIXING CEMENT TO DREDGED MARINE CLAY
The investigation for producting the high strength solidified soils of 10 MN/m 2 or more by mixing cement with dredged marine clay has been conducted. According to the results of the mix-proportion tests, in the case of Nagoya port clay, when the water cement ratio was set to 1.2 and the water content was set to 60 to 100%, the strength of 10 MN/m 2 or more could be secured. In addition, in a production experi-ment of solidified soil block, a biaxial forced mixing mixer was used assuming construction on site. The constraint condition for producting a solidified soil block using this mixer was to secure fluidity for push-ing out the treated soil from the opening of the mixer. As a result of fixing the water cement ratio to 1.2 and increasing the water content, it was possible to produce a solidified soil block at the water content of about 107% and the strength of core samples taken from the solidified soil block was 10 MN/m 2 or more. 75
