BestFlow A380

High-range superplasticizer, rapid strength development for concrete

  Advantages:
As a superplasticizer:

  • Strong flow concrete with extremely low water/cement ratio.
  • Self-compacting, easy to apply, no need for compaction... 
  • Increase density, improve surface quality.
  • Significantly reduce shrinkage and cracking of concrete.
  • Increased waterproofing for concrete.
  • Suitable for climate conditions in Vietnam.
As a strength enhancer:
  • Significant increase of early and final strength of concrete.
  • Shorter placing time and accelerated the progress of projects.
  • Shorten the time, speed up the construction progress, and reduce the cost of concrete maintenance.
  • Does not contain chloride, so it can be used without restriction for reinforced concrete structures.

  • BestFlow A380 is a 3rd generation high-range superplasticizer, derived from the polycarboxylate ether.
  • BestFlow A380 has the effect of greatly reducing the amount of mixing water, shortening the setting time, and promoting the development of very fast and very high strength, especially in the beginning.
  • BestFlow A380 conforms to TCVN 8826-2011 class F.
  • Cantilevered concrete. 
  • Precast. 
  • Self-compacting concrete.
  • Pre-stressed concrete
  • Super high-strength concrete, dense reinforcement.

  • BestFlow A380 can be added directly to the pre-quantified water before being added to a dry concrete mixture.
  • When added directly to wet concrete (pre-mixed with water), the plasticizing ability of the product will increase significantly and the minimum mixing time must reach 120 revolutions of the mixing tank (or mixing pad).
  • Should use a forced mixer machine.

Overdosing: 

  • When overdosing can lead to increased water separation and strong stratification, the setting time of the concrete can be prolonged (depending on the degree of overdose, the type of cement, and the grade of the concrete...). However, if the concrete is properly cured, the mechanical properties of the concrete will not be affected.
  • Note: Because the setting time of concrete can be prolonged, it is necessary to ensure that the concrete is properly cured and does not shake the formwork and reinforcement during the time when the concrete has not been set.

Health and Safety:

  • BestFlow A380 could have an allergy to sensitive skin if the contact for a long time. 
  • Should wear labor protection when the application. 
  • 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.
