Rockbond Quickbed Concrete (RB QBC)

Product Information Sheet:

Description

ROCKBOND QUICKBED CONCRETE (RB QBC) powder contains a blend of fine cement powders, high quality graded sands and aggregates and a union of admixtures. The compound, when mixed with water, produces a 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 2 years.

Special Properties

  • Quickly and easily mixed with water, poured and placed.
  • Ideal consistency for bedding in applications: non flowing, non slumping and thixotropic.
  • Portland cement based, shrinkage compensated and microsilica enhanced.
  • Quick setting and early strength: 4MPa at 2 hours at 20ºC.
  • High ultimate compressive strength: 60MPa at 28 days at 20ºC.
  • Can be used down to 0ºC, and placed in sections of up to 75mm.
  • Excellent bond strength, and resistance to abrasion and mechanical attack,
  • 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.

Uses

  •  In situations that require a non flow concrete with an early gain in compressive strength.
  • Bedding in applications that require early strength such as crash barriers, fence posts, signposts, manhole covers and rings, kerbs, coping stones, drains and precast elements.
  • Quick return to use of floors, paths, roadways and carriageway concrete.
  • Repairs to factory floors, car parks, forecourts, loading bays and ramps that require early trafficking.
  • For quick installation in areas where damage is caused by vandals and children.
  • For minimal disruption and delay during winter weather work.
