用湖南省常宁县水口山铅锌矿出产的铅锌原矿石制备了混凝土粗骨料,按混凝土粗骨料总质量的20%、40%、60%、80%、100%掺入卵石骨料中,制备了铅锌原矿石骨料混凝土.试验表明铅锌原矿石骨料混凝土拌合物的坍落度随原矿石骨料掺入比例的增加而降低,比例超过60%时,坍落度降低明显.混凝土抗压强度随原矿石骨料掺入比例的增加而降低.原矿石骨料掺入比例越高,混凝土对γ射线的吸收系数μ越大,对γ射线的屏蔽能力越好.

Lead-zinc ore raw aggregates were produced from Shuikoushan lead-zinc mine in Changning county,Hunan province.Lead-zinc ore aggregates concretes were prepared with the ratio of raw ore aggregates to total aggretes in 20%,40%,60%,80%,100%. Results showed that slumps of raw lead-zinc ore concrete with ratio of 20%,40% were basically the same as that of pebbles concrete. Slumps decreased gradually with the ratio of 60%,80%and 100%.The compressive strength of concrete decreased with the increasing of raw oreaggregates.The higher ratio of raw ore aggregates,the greater absorpt...
