Usage of Iron Mine Tailing Sand on Concrete

Abstract:

Two iron mine tailing sands and manufactured sands with different fineness modulus are studied and they are mixed into four mixed sands which fineness modulus is 2.6~3.0 by controlling mixing amount of iron mine tailing sand. The influence of mixed sands on workability and strength of C30 and C50 concrete are studied. The result shows that C30 and C50 concrete slump can reach 170mm. Concrete workability is good and strength is qualified too. Fineness modulus is the most important performance index when iron mine tailing sand is used in concrete.
