- Concrete is placed at lower slump,
or water reducing admixtures are used to increase
workability
- Evaporation retarders are utilized
Confilm, Eucabar, etc.
- All bleed water has evaporated prior
to any finishing, this is critical!!!
- The slab is finished with minimal
floating
- The surface is strick off, bull floated
and broomed
- Curling/Sealing compounds are applied
immediately following initial set and final finishing
pass
- Surface is protected from extreme
weather conditions (rain, freezing, low humidity,
+/- adequate temperatures)
|
|
- Water / cement ratio is increased.
Water is added to increase slump
- Spraying or blessing of surface with
a hose or brush
- Bleed water is finished into surface
of slab. This weakens the surface.
- The surface is overworked causing
the removal of air entrainment
- Power trowels, steel trowels, blue
gliders are used
- Slab is improperly cured
- Weather conditions are not accounted
