Crushing Strength Value Of Recycled Aggregates

Crushing Strength Value Of Recycled Aggregates

Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions. A Study On Recycled Concrete Aggregates. Crushing Value (ACV) and Aggregate Impact Value (AIV) are chosen as indicator of aggregate strength.

Influence of crushing index on properties of recycled

Influence of crushing index on properties of recycled

 · It means that it is feasible to use right amount recycled aggregates for making pervious concrete with acceptable compressive strength. According to Technical specifications for pervious concrete pavement (CJJ134-2009), when crushing index is smaller than 24% the compressive strength of RAPC are acceptable.
