BestFlow R322

BestFlow R322 is used for the following types of concrete:

• Ready-mixed concrete, long-distance transport concrete, long-time construction. 
• Mass concrete, concrete working in a hot climate.
• Concrete with compressive strength up to 50Mpa.
  

 As a superplasticizer: 

• Increases concrete mobility (slump) without increasing the water/cement ratio.
• Does not increase the risk of segregation (separation of water) during concreting. 
• Increase the plasticity of concrete, easy to construct, and easy to compact... 
• Increase the density of concrete, increase the waterproofing ability, and improve the concrete surface quality. 
• Minimize shrinkage, and cracking of the concrete surface. 
• Suitable for Vietnam's climate conditions.

 As a strength enhancer: 

• Significant increase in early strength and final strength of concrete.
• Allow reducing the dosage of cement without altering slump and concrete strength.
• Shorten progress and accelerated the progress of projects.
• Reduce the cost of concrete maintenance.

• ​BestFlow R322 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 R322 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.

Overconsumption :

• When overconsumption, its mobility will be increased (which might lead to bleeding), and the setting time will be extended. However, if a proper maintenance process must be ensured the physical performance of concrete and final strength will be not impacted.
  
• Note: 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 mix.
  

Cautions:

• Must be conducted a trial of concrete mix design in the Lab before use depending on the purposes. 
• Use the appropriate mixer and don’t mix by hand to ensure the consistency of concrete.

Reference formulation:

• Please consult the BestMix Technical Service for dosage rates to suit individual mix designs if required.
  

Health and Safety:

• BestFlow R322 is non-flammable. It could make an allergy to sensitive skin if the contact is in prolonging the time. Should wear labor protection when applying. 
• If eyes or mouth are affected wash with plenty of water and obtain medical attention immediately.
• Avoid contact with foodstuffs and utensils. Keep out of reach of the children.
