锂渣作为一种工业废渣利用到混凝土中,可发挥锂渣的潜能,提高混凝土的性能。试验利用了锂渣优良的可磨性,通过平板法开裂试验研究了不同细度锂渣对混凝土塑性收缩、自缩收裂缝的影响,并应用分形理论测量并计算不同细度锂渣混凝土裂缝的分形维数。结果表明:锂渣混凝土早期裂缝的最大宽度、总长度以及总面积随锂渣细度的增大而增大,同时裂缝复杂化程度提高。
As a kind of industrial waste residue, lithium slag is used in concrete, which can exert the potential of lithium slag and improve the performance of concrete. The experiment uses the excellent grindability of lithium slag. The influence of different fineness of lithium slag on the plastic shrinkage and self-shrinkage cracking of concrete is studied by the flat-plate cracking test. Fracture theory is used to measure and calculate the crack of lithium slag concrete with different fineness Fractal dimension. The results show that the maximum width, total length and total area of early cracks of lithium slag concrete increase with the increasing of the fineness of lithium slag, meanwhile, the crack complexity increases.
