Cellular Concrete
Pogo Mine Maintenance Shop
Overview
2007 - ACT drove mixer truck, concrete pump and equipment 400 miles to Pogo Mine, which is 60 miles east of Delta Junction, deep in the Alaska Range, to produce and place close to 100 yards of cellular grout.
The owner supplied cement in super bags and ACT supplied equipment, chemicals, and personnel to produce and inject grout under the maintenance shop floor to fill the void.
Low-density grout was used as an insulation barrier between frozen ground and the warm shop floor. In addition to filling the void, the sinking 12 inch thick reinforced slab was also jacked back up about 6 inches, taking 3 days.
Cellular Concrete
Overview
Cellular concrete, also known as 'lightweight grout', can be useful for many purposes:
- In-floor heating of buildings
- Insulating grout to act as barrier between permafrost and buildings, roads, bridge abutments, and pipelines.
- Void fills and Slabjacking where lo-density grout is needed
- Slipline and pipe abandonment where a highly fluid grout is needed to travel long distances or through small openings.
