NIROCRETE 1505 is a unique combination of the latest generation superplasticisers , based on a polycarboxylic ether polymer with long lateral chains, have very high water reduction and very long workability retention power. The product has been specially developed for applications in ready mix and site-batched concrete, where long retention is needed. NIROCRETE 1505 allows considerable reduction of mixing water while maintaining control on extend of set retardation thus improve the compressive strength of concrete and mortar without increasing the cement content. It makes concrete more impermeable and durable.
