为研究大掺量下锂渣混凝土的性能,采用氯离子渗透、吸水动力学、活性评价等方法分析了碱锂渣混凝土的力学性能、氯离子渗透性能、孔结构参数和活性因子。结果表明,锂渣掺量在40%以内时,掺碱混凝土的活性因子、抗压强度均较未掺碱时大;掺碱后混凝土的孔径均匀性较不掺碱时更大,平均孔径则更小;碱的使用激发了锂渣活性,有利于大掺量锂渣的利用,为利用碱锂渣制备混凝土提供了理论参考。 In order to study the properties of high-volume lithium-slag concrete, the mechanical properties, chloride ion permeability, pore structure parameters and activity factors of alkali-lime slag concrete were analyzed by chloride ion penetration, water absorption kinetics and activity evaluation. The results show that when the content of lithium slag is less than 40%, the activity factor and compressive strength of alkali-doped concrete are higher than those without alkali; Smaller; the use of alkali activated lithium slag activity, is conducive to the use of high-volume lithium slag, which provides a theoretical reference for the use of alkali-lithium slag preparation of concrete.
