Abstract: Focusing on several typical inferior sands in engineering, the sand of washing dry river bed, the Luomahu sand and the manufactured sands of shale and gneiss were discussed on their influence on concrete, including fresh concrete performance and mechanical property. The results show that, the Luomahu sand which has the least mud content has the most demand of polycarboxylate superplasticizer, and it has the highest slump loss. The small amount of silt content of washing dry river bed sand has little effect on bleeding rate and mechanical strength of concrete. Both of the manufactured sands have higher bleeding rate and lower air content than the river sands. The concrete of gneiss manufactured sand has the lowest compressive strength, and the bleeding rate reduces and the gap of concrete compressive strength between gneiss manufactured sand and river sand become wider as the concrete grade increases.
