Abstract

The invention relates to a method of preparing fres concrete for corrosion-resistant iron-reinforced concrete, wherein the iron reinforcement is protected against corrosi by adding an oxidising agent and a base. After an iron rein forcement has been imbedded in the fresh concrete and the fresh concrete has set, it protects the iron reinforcement against corrosion. The invention also relates to a method o manufacturing corrosion-resistant iron-reinforced concrete using the fresh concrete of the invention.
