Abstract
A concrete mix useful for producing concrete products having anti-efflorescence properties and a method for making such concrete products are provided. The concrete mix includes a hydraulic cement binder, aggregates and as an additive an ultrafine particulate material including carrier particles being surface treated with an efflorescence control agent. The method for making concrete includes a first step of mixing the hydraulic cement binder, aggregates, water and the ultrafine particulate material, a second step of pouring the mixture so obtained into a form, and a third step of curing the mixture.
