PROCRETE R80 is a high performance uperplasticiser intended for ultra-high strength concrete having very low water cement ratio and long workability retention are required. It is a unique combination of the latest generation superplasticisers, based on a polycarboxylic ether polymer with long lateral chains. Upon mixing with concrete, occurrence of electrostatic dispersion will allow cement particles to separate each other. This mechanism considerably reduces the water demand in flowable concrete.
