[摘要]通過對4根鋰渣摻量為15%的鋼筋混凝土短柱與4根普通鋼筋混凝土短柱在模擬酸雨環境下進行不同周期腐蝕后的軸壓試驗,對比鋰渣混凝土與普通混凝土耐酸雨腐蝕性能的區別,研究鋰渣混凝土受酸雨侵蝕的規律。試驗結果表明,鋰渣混凝土與普通混凝土受酸雨的侵蝕規律相似,兩者的耐酸雨腐蝕能力十分接近,鋰渣鋼筋混凝土短柱承載力下降程度略高于普通鋼筋混凝土短柱。研究成果可為鋰渣混凝土在實際工程中的推廣使用提供參考。

Abstract:Through the axial compression tests of four reinforced concrete short columns with 15% lithium slag and four ordinary reinforced concrete short columns with different corrosion cycles under simulated acid rain, the differences of acid rain corrosion resistance between lithium slag concrete and ordinary concrete were compared, and the rule of acid rain corrosion of lithium slag concrete was studied. The test results show that the corrosion regularity of lithium slag concrete is similar to that of ordinary concrete under acid rain. The corrosion resistance of lithium slag reinforced concrete  is very close to that of ordinary concrete. The bearing capacity of lithium slag reinforced concrete short columns decreases slightly higher than that of ordinary reinforced concrete short columns. The research results can provide reference for the popularization and application of lithium slag concrete in practical engineering.

Keywords:lithium slag; simulated acid rain corrosion; reinforced concrete; bearing capacity
