Placement Solbow Joint Venture (PSJV) is managing concrete waste at the Lihir operations and in doing so, saving costs.
PSJV use concrete bar chairs during construction work, especially to hold the reinforcing steel bar (called rebar) above the ground so it ends up in the middle of the concrete foundation when the concrete is poured.
Without the chairs, the rebar would sit on the ground and would be exposed to water and rust. Additionally, it will not hold the concrete together.
