【摘要】:利用壓汞法(MIP)測試了不同鋰渣摻量的C30、C60混凝土的孔結(jié)構(gòu)參數(shù),計(jì)算了被測混凝土的孔體積分形維數(shù)、孔軸線分形維數(shù),并研究了混凝土氣體滲透系數(shù)、鋰渣摻量與孔體積分形維數(shù)、孔軸線分形維數(shù)之間的關(guān)系。結(jié)果表明,混凝土的氣體滲透系數(shù)與孔體積分形維數(shù)相關(guān)性高;C60混凝土在鋰渣摻量為10%時(shí),孔體積分形維數(shù)和孔軸線分形維數(shù)最大;隨著鋰渣摻量的提高,C30混凝土孔體積分形維數(shù)和孔軸線分形維數(shù)呈降低的趨勢。
[Abstract]:The pore structure parameters of C _ (30) C _ (60) concrete with different lithium slag content were measured by (MIP) method. The pore volume fractal dimension and pore axis fractal dimension of concrete were calculated, and the gas permeability coefficient of concrete was studied. The relationship between the content of lithium slag and the fractal dimension of pore volume and pore axis. The results show that the correlation between the gas permeability coefficient and the fractal dimension of pore volume is high. When the content of lithium slag is 10, the fractal dimension of pore volume and the fractal dimension of pore axis are the largest. With the increase of the content of lithium slag, the fractal dimension of pore volume and the fractal dimension of pore axis of C30 concrete decrease.
