锂渣复合矿物掺合料对胶凝材料强度的影响

Effect of Lithium Slag Composite Mineral Admixture on the Strength of Cementitious Materials

研究锂渣与其他矿物掺合料复掺对胶凝材料强度的影响,通过不同锂渣粉与不同矿物掺合料分别复合,测试胶凝材料早期和后期抗折和抗压强度。试验结果表明:与单掺锂渣粉的胶凝材料相比,锂渣粉分别与粉煤灰、矿渣粉和硅灰三种矿物掺合料复合,可以提高胶凝材料早期和后期强度;而锂渣粉与矿渣粉复掺时,其复合叠加效应优于锂渣粉与粉煤灰或硅灰复掺。

This paper studied the influence of lithium slag composite admixture on the strength of cementitious materials.Different lithium slag powders were combined with different mineral admixtures to test the early and later flexural and compressive strength of cementitious materials.The test results show that,compared with the cement material with only lithium slag powder,the lithium slag composite admixture with three mineral admixtures of fly ash,slag powder and silica fume,can improve the early and late strength of the cement material;and When the synergistic effect of lithium slag composite powder is stronger than that of the other two admixtures.
