The Influence of Size and Layer Face Effects on the Deformation Performance of Fully-graded RCC

摘要

This study conducts comparative tests of compressive elastic modulus,ultimate tension,autogenous volume deformation and creep,etc.on fully-graded RCC with and without layer face and wet-screened two-graded RCC.The results indicate that the ultimate tension,autogenous volume deformation and creep of fully-graded RCC are smaller than those of wet-screened two-graded RCC,which is affected by wet-screened size.The influence of layer face on ultimate tension of fully-graded RCC is larger than that on compressive elastic modulus.
