Steel reinforced post-filling coarse aggregate concrete ...

Feb 08, 2021  Post-filling coarse aggregate concrete (PFCC) is a new type of environmental friendly concrete. The increase of coarse aggregate content could decrease the shrinkage of concrete, reduces the consumption of cement in concrete production, reduce the carbon dioxide emission to the environment and saves energy.

Properties of steel fibre reinforced concrete containing ...

Jan 01, 1995  However, up to now the steel fibre reinforced concrete used extensively is rich concrete with small coarse aggregate of maximum size of 10, 15 or 20 mm. The increase of cement content certainly causes the increase of shrinkage and cost of the concrete. Small and less coarse aggregate in concrete is also unfavourable for the abrasion resistance.
