摘　　要：对C30和C50两个强度等级的混凝土进行不同水淬锰铁合金渣掺量试验,测试其强度变化趋势。通过对比,研究水淬锰铁合金渣混凝土和普通混凝土干缩率。结果表明,C30混凝土中水淬锰铁合金渣掺量可达到40%,C50混凝土中水淬锰铁合金渣掺量可达20%,且水淬锰铁合金渣混凝土的干缩率小于普通混凝土的收缩率。Concretes of C30 and C50 were prepared with different content of ferromanganese slag,to test their tendencies of compressive strength.The drying shrinkage of concrete containing ferromanganese slag and ordinary concrete were tested and compared.The results showed that the dosage of feromanganese slag in C30 and C50 concrete could be up to 40% and 20% respectively. The drying shrinkage rate of concrete prepared with ferromanganese slag was smaller than ordinary concrete.
