  Recyclability of Broken Pile Head Concrete in Structural Use
  Author(s): H A Rashid*, B A Nur and R Ahsan
  
  To improve sustainability, the use of recycled concrete aggregate in the construction industry has increased globally. Urban areas are experiencing a critical shortage of natural aggregate for concrete production. Recycling construction and demolition waste, generating recycled aggregates and using them as an alternative material, could be a solution. This paper presents the recyclability of broken pile head concrete in structural use. The broken pile heads were collected from various sources of newly constructed structures and crushed to a suitable aggregate size with a mechanical crasher. Laboratory tests were conducted on both recycled and virgin aggregate. The test results revealed that aggregate gradation, aggregate crushing value, ten percent fine value, abrasion, rodded unit weight, flakiness index, elongation, wash passing, water absorption, clay lumps and friable particles, s..
