Vacuum O-ring brush finishing
Vacuum O-ring brush finishing
Construction method outline:
With this method, we cover the concrete area directly after placing with a vacuum mat to form a vacuum on the floor surface, and physically remove excessive water inside the concrete, which is unnecessary for hydration reaction, with a vacuum pump.
- Advantage of dehydration construction method
Increase of initial strength and surface strength, reduction of hardening shrinkage (cracking),
increase of abrasion resistance, freezing damage resistance, short construction period
- Tool
Leveling hoe, aluminum scale, ring scale, wood trowel, metal trowel, aluminum footgear
- Machine
Vacuum pump, vacuum mat, O-ring, trowel (machine trowel)
- Protection tool
Safety helmet, safety belt, safety shoes, safety boots
Construction process
Concrete needs curing period after placing. The vacuum construction method allows reduction of the curing period.
For example, when the conventional method needs 1 week (7 days), the vacuum construction method needs just 3 days. Similarly, 4-week (28 days) curing period can be shortened to 7 days.
