ROCKBOND QUICKBED CONCRETE (RB QBC) powder contains a blend of fine cement powders, high quality graded crushed rock sands and aggregates and a union of admixtures. The compound, when mixed with water, produces a thixotropic, non slump, non flow, quick strength, high strength concrete, which has been specially designed for bedding in applications. The powder is pre-mixed, ready to use, packaged in 25kg moisture proof durable bags and has a shelf life of 5 years.
Portland cement based, shrinkage compensated and microsilica enhanced.
Quickly and easily mixed with water, poured and placed.
Ideal consistency for bedding in applications: thixotropic, non slumping and non flowing.
Quick setting, and with an early strength development: 4MPa at 2 hours at 20ºC.
High ultimate compressive strength: 60MPa at 28 days at 20ºC.
Non shrink, anti slip, non crazing, non cracking, non curling and non dusting.
Can be used down to 0ºC, and placed in sections of up to 75mm.
Hard wearing, long lasting and resistant to mechanical attack, impact and abrasion.
Contains no chlorides, high alumina cement or other deleterious substances.
High yielding, economical, non flammable, non toxic, odour free, user friendly and safe to use.
In situations that require a non flow concrete with an early gain in compressive strength.
Bedding in applications that require early strength such as precast concrete units, crash barriers, fence posts, signposts, manhole covers and rings, paving slabs, kerbs, coping stones, drains, frames and bricks.
For the quick return to use of paths, floors, roadways and carriageway concrete.
Repairs to factory floors, car parks, forecourts, loading bays and ramps that require early trafficking.
For the quick installation of concrete furniture in areas where damage is caused by vandals.
For minimal disruption and delay at low temperatures or during winter weather work.
