| Abstract: | Based on the computer image processing technology,the pore structure from CT images of recycled concrete with lithium slag was extracted.The porosity,fractal dimension and shape factor of cube specimens with different recycled coarse aggregate replacement rate and different lithium slag content were calculated and counted by IPP and FractalFox software,and the relationship between the three factors and cube compressive strength was studied.The results show that the porosity and compressive strength of recycled concrete with lithium slag satisfy the cubic equation relationship.There is a good correlation between the pore shape factor and compressive strength within a certain range. |
