NIROCRETE ULTIMA 2500 is the superplasticiser based on new generation polycarboxylic ether polymers, developed using special polymer-technology, which is the ultimate solution of High performance and High-grade concrete. It has very long retention power and also 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
