Investigation of Drying Shrinkage of Concrete Prepared with Iron Mine Tailings

Abstract:

Article Preview

Concretes of C30 and C60 were prepared with iron mine tailings as fine aggregate and coarse aggregate and with natural sand and common crushed stone separately. The drying shrinkage of concretes cured under the natural condition in the laboratory was tested. The results showed that whether C30 or C60 the drying shrinkage of concrete prepared with iron mine tailings was a little smaller than that of concrete with natural sand and common crushed stone. It was also found that whether the concrete with iron mine tailings or the concrete with natural sand and common crushed stone the drying shrinkage of C60 concrete was larger than that of C30 concrete.
