锰渣掺合料对混凝土耐久性影响的研究

Research on the durability of concrete with ferromanganese slag admixture

研究锰渣掺合料对混凝土性能的影响。研究了锰渣掺合料替代20%水泥时,锰渣混凝土强度高于基准混凝土,工作性能良好,干缩得到明显改善,保持良好的体积稳定性,提高了混凝土的抗渗性,且抗冻性能优于基准混凝土。

The ferromanganese slag admixture for concrete was researched.With 20 percent of ferromanganese slag added,strength of Manganese slag concrete at 28 d is higher than the reference concrete,and its workability is good.The drying shrinkage rate,anti-permeability and frost resistance are enhanced greatly.
