摘要: 利用工业废渣开发的新型胶凝材料,对尾砂的固结效果远远超过了水泥。为了验证开发的新型胶凝材料的可靠性和稳定性,开展了现场试验。利用新型胶凝材料和32.5#水泥2种胶凝材料,进行不同胶砂比和不同质量浓度的全尾砂充填胶凝材料的28 d强度试验。试验结果表明,在任何胶砂比、任何浓度条件下,新型胶凝材料充填体强度均高于相同条件下的32.5#水泥充填体。说明新型胶凝材料对全尾砂的固化效果好,为矿山尾矿的资源化利用找到了一条新途径。

Abstract: A neotype cementing material was developed by using industrial residue,and its consolidation of whole-tailings exceeded the cement.Field mechanical experiment was carried out in order to test the reliability and the stability of the neotype cementing material.The effect of different cement-sand ratio and different mass concentration on the 28d compress strength of neotype cementing material and 32.5# cement was investigated.Results show that: the strength of neotype cementing backfilling body is higher than the 32.5# cement backfilling body at the same condition.The solidification effect of whole-tailing using neotype cementing material is better,which provides a new approach for reutilization of mine tailing.
