摘 ? 要:基于計算機圖像處理技術,從摻鋰渣再生混凝土的CT圖像中提取出孔隙結構,利用IPP和FractalFox軟件對不同再生粗骨料取代率和不同鋰渣摻量立方體試件的孔隙率、分形維數、形狀因子進行了計算與統計,并對孔隙特征與立方體抗壓強度進行了關聯性研究。結果表明:摻鋰渣再生混凝土的孔隙率與立方體抗壓強度滿足三次方程關系;一定范圍內,孔隙形狀因子與抗壓強度之間的關聯性良好。
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.
