Hydroflux plasicizes concrete mixtures and keeps the permament consistence. It reacts with carbonates and causes the tightening of concrete mixtures. By using PN86/BO6712 "Mineral concrete aggregates", PN88/BO6250 "Normal concrete" and Hydroflux, concrete can reach the water pressure strength up to 6 atm. Concrete and mortar made with usage of Hydroflux are freezeproof. Hydroflux facilitates pumping and overflowing of concrete. It reduces washing the concrete mixer and pumps. It doesn't change the colour of the concrete mixture.
