Fosroc Resivit | Concrete & Mortar Setting Accelerator

Fosroc Resivit

2282002
FOS8087

Fosroc Resivit is a liquid admixture which is added to mortars and concrete during production in order to accelerate their setting and hardening to quickly attain increased mechanical resistance.

  • Complies with BS EN 934-2, BS 5075 Part 1 and with ASTM C494 Type C
  • Acts as a catalyst in the initial hydration reactions of the cement, particularly at low temperatures. The set is accelerated and mechanical resistance develops rapidly, which limits damage to fresh concrete caused by frost

Features & Benefits


  • Particularly effective in assisting to offset the delaying effect of low temperatures on setting and strength gain
  • If used in conjunction with superplasticisers the combination of early set and strength gains achieved can enable double casting in a single shift
  • Accelerated setting reduces the risk of damage to fresh concrete from freezing
  • Chloride free, safe for use in reinforced concrete
  • The efficiency of Resivit is particularly useful where fast stripping of the moulds is required

Uses

  • To accelerate the stiffening and early strength gain of Portland cement concretes and mortars
  • Typical applications for concrete or mortar placed in cold weather
  • Readymix concrete
  • Precast concrete
  • Pre-stressed concrete
  • Grouts



Application Notes


  • Compatible with other Fosroc admixtures in the same concrete mix. The performance of concrete containing more than one admixture should be assessed by trial mixes to ensure the desired combination of effects is obtained
  • Suitable for use with ordinary Portland cement
  • Chloride free and therefore can be used in steel reinforced concrete
  • The correct quantity should be measured by means of a recommended dispenser
  • As with all structural concrete, good curing practice should be maintained. Water spray, wet hessian or a Concure spray applied curing membrane should be used
  • Freezing point: Below -10°C
  • Available in 20 litre drums



Limitations


  • The use of Resivit does not mean that normal concrete practice when concreting in cold weather can be ignored
  • An overdose of double the intended amount of Resivit may result in increased acceleration. In common with other accelerators this may slightly reduce the ultimate strength of the concrete
  • Resivit is an oxidising agent and should be stored away from reducing agents and combustible materials
  • If freezing of the product does occur it is important that it is fully reconstituted before use
  • Resivit is water based and non-flammable but should be stored away from combustible materials
