Geotechnical Applications
Lightweight Concrete flows with ease and there is no need for compacting, it is ideal for all kind of void filling applications.
Benefits:
- High slump (virtually self-leveling).
- Inert.
- Broad range of densities and compressive strenghts.
- Excellent freeze-thaw resistance.
- Low water absorption and low permeability.
- Insulating (can contain up to 80% air).
- Rapid installation.
- Economicall load reduction.
- Long lasting and stable.
- Places easily by pump or gravity.
- Positive fill (flows to fill all spaces available).
- Absorbs shock waves.
In pipeline construction, these applications may include abandonment fills, annular fills for sliplined pipes, fills between both a pipe and a tunnel cut as well as pipe and a cribbed excavations.
Other void fill applications include:
- Sinkholes.
- Fill settlement voids under slabs.
- Fills voids within silos, abandoned mines, underground tanks and pipelines.
- Foundation fills.
- Replaces unstable soil to reduce subsistence of roadways, bridge ramps and other structures.
- Provides shock absorption in earthquake zones.
- Reduces loads above underground structures.
- Reduces hydrostatic pressure on retaining walls.
