摘　　要：以黄金尾矿和石灰石为原料,煅烧制备了高贝利特相混凝土掺和料(JS掺和料).研究了用JS掺和料配制的C80混凝土的工作性和力学性能.结果表明,与普通C80混凝土相比,用JS掺和料配制的C80混凝土具有与试验减水剂适应性好、坍落度损失小、保水性好等工作性能,且其早期、中期和后期抗压强度高,28 d弹压比小.A belite-rich mineral admixture（JS admixture） for concrete was prepared by sintering gold mine tailings and limestone. The working performance and mechanical properties of C80 concrete with JS admixture added were investigated. The results show that the C80 concrete with JS admixture added has better performance than the traditional C80 concretes in terms of the working performance, the compressive strength and other mechanical properties（including ratio of modulus of elasticity to compressive strength）.
