Abstract: Based on steel slag as an active admixture for concrete industry,C30 concrete was prepared with waste utilization of steel slag powder and slag powder,which were produced by Yunnan Kunming Steel Industry Development Co.. Mixed concrete and steel slag powder flow ability and slump loss of concrete were studied.Slag powder and naphthalene and polycarboxylate adapt ability were explored.The results demonstrate that the incorporation of slag powder does not affect the suitability of concrete superplasticizer,but helps to reduce the concrete slump loss.

Key words: steel slag powder, concrete, slag powder, fluidity
