a lightweight material made by replacing some or all of the stone aggregate used in standard concrete.
Low density cellular concrete (LDCC) is a lightweight material made by replacing some or all of the stone aggregate used in standard concrete with uniform air cells (voids). These air cells are created by blending foaming agents into the concrete during the mixing process, and can be managed to produce an engineered geotechnical material. Its density can be varied from 20 to 120 lbs. per cubic foot, and its compressive strength from 20 to 3000 psi. Geotechnical applications include load-reducing fill, backfill for tunnels and retaining walls, annular grouting for tunnels, fill for bridge approaches, and fill for sinkholes and abandoned underground tanks, pipelines and mines. LDCC can be produced in both pervious and non-pervious blend.
