What Is Bleeding in Concrete and How It Affects Concrete ...

Due to bleeding concrete loses its homogeneity. Bleeding is responsible for causing permeability in concrete. In the process of bleeding (i.e. while water is in the process of coming towards top) sometimes gets accumulated below the aggregate. This accumulation of water creates a water voids and reduces bond between the aggregate and cement past.

This paper presents an experimental research on mechanical properties of recycled aggregate concrete (RAC) at low and high water/binder (W/B) ratios. Concrete at two W/B ratios (0.255 and 0.586) was broken into recycled concrete aggregates (RCA). A type of thermal treatment was employed to remove mortar attached to RCA. The RAC at a certain (low or high) W/B ratio was prepared with RCA made ...
