Monitoring method of setting behavior and quality control of retarded solidified soil cement materials
Takashi Ootani and Yasushi Fujiwara
Methods of confirmation of setting time and setting behavior for soil-cement mixtures controlled setting time, such as bentonite slurry material and soil cement, are important. In this laboratory test, properties of retarded solidified soil cement before hardening were measured, changing content of retarding admixture. At result, the combination of change of temperature and shear strength (0.17~33.4 kN/m2) measured by hand-vane shear test made confirmation of setting time and setting behavior possible. These properties are proposed for indexes of quality control of setting time of retarded solidified soil cement.
