DUOSOL VMA-7 is a new generation concrete mix viscosity modifier. DUOSOL VMA-7 allows concrete to achieve optimal viscosity, providing the right balance between flexibility and delamination resistance - the opposite properties that appear when adding water. DUOSOL VMA-7 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.
Dosage: from 1.5% to 3.0% by weight of the finished additive based on polycarboxylate ether. The optimal dosage of DUOSOL VMA-7 is achieved through trial mixes and depends on the amount of cement and fillers included in it. Despite the fact that DUOSOL VMA-7 is very stable at all pH values and concentration of additives, we recommend stirring the additive for long-term storage.
