EXPERIMENTAL STUDY ON THE STRESS-STRAIN CURVE OF CEMENTITIOUS GROUT UNDER UNIAXIAL COMPRESSION |
| |
| Abstract: | Based on the constitutive tests of cementitious grout( CG),the effects of type of CG,amount of water and pisolite on the stress-strain curve,Poisson's ratio,volumetric strain,and peak strain of CG are investigated.Besides,through the comparison of the uniaxial compressive stress-strain curve of CG and that of concrete,the similarities and differences between them are obtained,and the stress-strain constitutive equations of CG in different mix proportions are given. |
