摘　　要：锰渣作为生产锰铁合金的副产物,被当作工业废弃物堆积、填埋,所以将其作为混凝土掺合料有效的资源化利用具有重要意义。对C40混凝土进行不同锰渣掺量的试验,测试其强度变化趋势,并以掺有20%锰渣的C40混凝土作为试验基础,着重研究在高效减水剂配合下大掺量锰渣混凝土强度试验。Manganese slag-as a byproduct of producing manganese ferroalloy,was piled up and landfilled,therefore it has important signifi- cance to use it effectively as concrete admixtures.In this research,the C40 concrete with different content of manganese slag were experimented,to test their changing tendencies of compressive strength,and C40 concrete with 20% manganese slag was experimented as sample.In cooperation with superplasticizer,the concrete with much larger amount of manganese slag was experimented to test compressive strength.
