New lightweight concrete materials for road and bridge filling

Foam concrete has the advantage of fast construction speed, which can effectively save the construction period. The foam concrete is used for filling, the filling body exerts little load on the foundation, and there is no filling settlement after construction. foam concrete is a new lightweight concrete material that can replace soil for filling the abutment back.

Foam concrete is lightweight as road and bridge filling materials; Insulation, thermal insulation, and anti-corrosion; High fluidity before molding; Fill self compacting; Adjustable density and strength; Upright after solidification; Compressible, low elasticity seismic resistance; Good durability and other characteristics.

It is also applied to other roads and bridges of foam concrete, such as soft soil subgrade filling, bridge span reduction, mountain road subgrade, road widening, foundation pit filling, underground structure engineering upper load reduction, tunnel, pipeline filling, etc.
