为了提高混凝土抗氯离子渗透能力,在混凝土中掺入具有火山灰性的锂渣和会产生自身水化的钢渣。采用正交设计,通过RCM法测试表明,随着锂渣和钢渣掺入总量的增加,混凝土抗氯离子渗透的能力呈现先增大后减小趋势,以锂渣掺量为25%和钢渣掺量为20%时为最优掺量。在水泥水化后,锂渣参与了二次反应,细化了混凝土界面结构,同时促进了钢渣和水泥的相互水化程度,提高了混凝土抗氯离子渗透的能力。
In order to increase permeability of resistance to chloride ion of high performance concrete, me lithium slag with volcanic ash usability and steel stag producing their own hydration were mixed with the concrete. Using orthogonal design,RCM method tests showed that with the incorporation of lithium slag and steel slag increase in the total, concrete resistant to chloride ion penetration ability first increases and then decreases. Lithium slag dosage for 25% and 20% steel slag was regarded as the optimal dosage. After cement hydration,Lithium slag participated in a secondary reaction,the interface structure of concrete was refined,at the same time the mutual degree of hydration of the steel slag and cement was promoted,the ability of concrete resistance to chloride ion penetration was improved.
