SikaRapid® AF

Ac - Non Chloride Set Accelerator

 

SikaRapid® AF is a non chloride set accelerator for concrete and mortar.

Can be used alone or in conjunction with a water reducer or a superplasticiser. Faster demoulding Reduces the risk of damage by freezing when pouring with cold temperature by shortening the plastic phase of the concrete.

Usage

SikaRapid® AF is recommended for use in premix and precast concrete where accelerated setting time is required. As a result, SikaRapid®-AF allows:
  • Faster finishing of concrete surfaces.
  • Improved early strength of premixed concrete.
  • Faster slip-form movement.
  • Used in ready mix concrete in cold weather.
 

Advantages

System information

Compatibility

SikaRapid® AF can be used in conjunction with any non-retarded Sika plasticiser or superplasticiser. It is beneficial to add SikaRapid® AF with the initial mixing water before the addition of superplasticiser to enhance strength development. Tests must be carried out to determine the optimum combination.

Do not useSikaRapid® AF in conjunction with shrinkage compensating admixtures.

Application

Application Information

Dispensing

SikaRapid® AF is added to batching water or is poured into the concrete mix at the same time as the gauging water. SikaRapid® AF may also be added into the agitator truck on site. In this case, the concrete should then be mixed for an extra 1 minute for every cubic metre of concrete. The concrete should then  be checked visually for uniform consistency before discharging.
Consumption

Recommended dosage

Dosage is 400ml - 2000ml/100 kg of total cementitious material. Exact dosage rate should be determined by site trials.
