Application

TOP-VMA-II is a new generation concrete mix viscosity modifier. TOP-VMA-II allows concrete to achieve optimal viscosity, providing the right balance between flexibility and delamination resistance - the opposite properties that appear when adding water. TOP-VMA-II improves the coherence of concrete components, so it is capable of prevent the segregation of the binder and fillers in the concrete mixture when pumping concrete, especially under high pressure.

Advantages

• Good flow properties with high concrete strength
• Prevents delamination and water separation Production of self-compacting concrete (SCC) without segregation and with a given viscosity
• High compatibility with polycarboxylate type hyperplasticizers
• Allows to pump concrete over long distances under high pressure
• Makes the solution less sensitive to the quality of the fillers
• Enhances water reduction
• Makes a concrete mix a Newtonian liquid
• Ease of use

Dosage

Dosage: from 1.5% to 5.0% by weight of the finished additive based on polycarboxylate ether. The optimal dosage of TOP-VMA-II is achieved through trial mixes and depends on the amount of cement and fillers included in it. Despite the fact that TOP-VMA-II is very stable at all pH values and concentration of additives, we recommend stirring the additive for long-term storage.
