【摘要】 用锂渣部分代替矿渣制备碱激发矿渣-锂渣混凝土,结果表明,当溶渣比(质量比)为0.5,0.6,胶凝材料用量为390 kg/m3时,碱激发矿渣-锂渣混凝土的28 d抗压强度大于70 MPa,且早期抗压强度高,3 d就都达到28 d的70%左右.同时,研究了碱激发矿渣-锂渣混凝土的工作性和氯离子渗透性.结果表明,该混凝土的工作性良好,抗氯离子渗透性高.更多还原

【Abstract】 The aim of this study is to use lithium slag to partly replace slag to make alkali-activated slag-lithium slag concrete.The results show that when m_WR/m_C is 0.5 or 0.6,and amount of cementitious material is 390 kg/m³,the 28 d compressive strength of concrete can reach 70 MPa（over,） and early strength is high and can reach about 70% of 28 d compressive strength.At the same time,the paper presents an investigation into workability,chloride ions permeability of alkali-activated slag-lithium slag concrete.The results show that the concrete have good workability and low chloride ions permeability.更多还原
