Mechanical and Failure Criteria of Air-Entrained Concrete under Triaxial Compression Load after Rapid Freeze-Thaw Cycles

The experiment study on the air-entrained concrete of 100 mm cubes under triaxial compression with different intermediate stress ratio α2=σ2D : σ3D was carried out using a hydraulic-servo testing system. The influence of rapid freeze-thaw cycles and intermediate stress ratio on the triaxial compress...
