Deformation Characteristics of Roller Compacted Concrete under Triaxial Stress State

Huai Liang Wang, Yu Qing Ren

Experiments of two graded-aggregates concrete used for RCC arch dam are conducted. The experiment includes three states: direct shear state, compressive-compressive-shear state and tensile-compressive-shear state. Comparison and analysis of the deformation characteristics of body specimens and layer specimens are carried out. Influences …
