Abstract
The additive for reinforced concrete is a concrete additive for preventing corrosion of steel rebars in steel-reinforced concrete, improving the workability of the cast concrete, and reducing water absorption/permeability in the cast concrete. The reinforced concrete may be a conventional reinforced concrete, such as that formed from a mixture of water, an aggregate and cement, having at least one steel rebar embedded in the mixture. The additive is added to the mixture prior to curing and casting. The additive may for example, have a concentration with respect to the cement of between 0.25 wt % and 1.0 wt %. The additive includes a triazole and a non-ionic surfactant including a poly oxy ethoxylated reaction product of sorbitan and a fatty acid. The triazole and the non-ionic surfactant are dissolved in the solvent.
