BestFlow R339

Super-plasticize and slump retention concrete admixture

Advantages:
As a superplasticizer:
  • Substantial improvement in flowability of concrete without increased water/cement ratio.
  • Long slump retention.
  • Avoidance the risk of segregation of concrete mix in place.
  • The increased plasticity of the concrete mixture makes it easier to work and vibrate...
  •  Reduced shrinkage. Suitability for climate conditions in Viet Nam.
As a strength enhancer: 
  • Significant increase of early and final strength of concrete.
  • Allow substantial cement reduction without altering slump and ultimate concrete strength.
  • Shorter placing time and accelerated the progress of projects.
  • Reduced expenses for curing concrete.
  • Do not contain chloride which destroys the steel. Do not limit reinforcement concrete.

  • BestFlow R339 is used as a highly effective superplasticizer with long slump retention, suitable for high-strength concrete in a climate conditions in Viet Nam. 
  • BestFlow R339 complies with TCVN 8826-2011 Type D&G.

BestFlow R339 is used for this concrete:

  • Ready-mixed concrete, long-distance transport concrete, long-time construction.
  • Mass concrete, concrete working in the hot climate.
  • Bored pile concrete, reinforcement concrete, floor concrete high strength.

As a superplasticizer:

  • Substantial improvement in flowability of concrete without increased water/cement ratio.
  • Long slump retention (≥ 4 hours). 
  • Avoidance the risk of segregation of concrete mix in place.

Dispensing: 

  • BestFlow R339 can be added directly to the pre-quantified water before being added to a dry concrete mixture or separately to the freshly mixed concrete. 
  • When added directly to wet concrete (pre-mixed with water), the plasticizing ability of BestFlow R339 will increase significantly and the minimum mixing time must reach 80 revolutions of the mixing tank (or mixing pad).
  • Possible to combine with other concrete admixtures but must be quantified and put into concrete separately for each type. Must be conducted a trial in actual conditions on site before use.

Overdosing:

  • When overdosed, its flowability will be increased (might be segregated to concrete mix), and setting time will be extended depending on the cement content and temperature. However, if proper curing must be ensured the physical performance of concrete and final strength will be not impaired.
  • Notes: Due to the extension of setting and hardening time the curing must be done properly. Don’t impact the steel reinforcement or framework during a set time of the concrete mixture.

Notice: 

  • Specific pre-mix testing is required for each use. 
  • Use mixers suitable for different types of mortar. The mortar should not be mixed by hand to ensure uniformity of the mixture.

Ref distribution: 

  • It is possible to request a consultation for each specific use from the company's technical staff when required. 

Health and Safety information: 

  • BestFlow R339 is non-flammable. PPEs must be worn when applying.
  • BestFlow R339 could have an allergy to sensitive skin if they contact for a long time.
  • If eyes or mouth are affected wash with clean water and go to medical attention immediately. 
  • Avoid contact with foodstuffs and utensils. Keep out of reach of the children.
