Abstract: HAS Tailing Solidified agent is a fly-slag cementing materials which blast furnace slag is raw materials.Total tail is solidified by different HAS solidified agent of different gypsum content.Compressive strength was studied to evaluate the quality of the solidified tail and the cement is compared to HAS solidified agent.Experimental and in-site result showed that HAS solidified agent can surpass the cement on the strength of solidified tail and the cost of HAS solidified agent is lower than cement.HAS solidified agent is an overflow tailing solidified agent.

Key words: HAS solidified agent, Solidification, Total tailing
