锂渣作为混凝土掺合料的可行性研究

Research on the Feasibility of Using Lithium Slag as Mineral Admixture in Concrete

本文主要研究了以锂渣作为掺合料对混凝土工作性能、抗压强度、早期抗裂性能的影响,并且分析了影响机理。试验结果表明:随着锂渣掺量的增加,混凝土坍落度出现一定的减小,而稠度出现相应的增加,混凝土的早期抗裂性能增强;从抗压强度角度考虑,锂渣在混凝土中存在的最优掺量是10%。

The influence of lithium slag as mineral admixture on the performance, compressive strength and early crack resistance of concrete was studied, and the reaction mechanism of lithium slag in concrete was discussed in this paper. The results showed that, with the lithium slag content increased, concrete slump was reduced, the consistency was increased, and the early crack resistance of concrete was reinforced. From the perspective of the compressive strength, the optimal dosage of lithium slag in concrete is 10%.
