Tilcon Installs Concrete Reclaimer at Plainville Plant
Section: Press Releases

Tilcon’s new concrete reclamation system has four washout stations where stone, sand and cement are recycled.

Tilcon Connecticut has recently installed a concrete reclaim system at the Plainville concrete facility. The concrete reclaimer is used to manage returned plastic concrete that has not been used at the jobsite.

The reclamation process involves mechanically separating the sand, stone, and cement from returned plastic concrete. In turn, the sand and stone are reused in fresh new ready-mix concrete and the cement and associated wash water is environmentally controlled and recycled. The reclaiming process offers substantial environmental benefits including the ability to recycle and reuse stone and sand along with fresh water savings and processed wash water management control.

The JADAIR concrete reclaimer works much like a sand wash plant. The recycling process begins when the concrete mixer driver pulls up to one of four washout stations and unloads the returned concrete into a steel troth filled with recycled wash water. The stone and sand settle to the bottom of the machine where paddles scoop up the aggregates and place them onto a conveyor. From the conveyor, the sand is screened from the stone and both exit into separate piles. The cement particles stay suspended in the water for a period of time and settle into a ‘clarifier’ chamber of the machine. Slow moving paddles pull the settled cement particles into a slurry pit where cement clay is deposited for drying. The reclamation process is a closed loop system designed to environmentally control and manage returned plastic concrete and mixer wash water.
