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.
