Abstract
Eight compounds were tested as inhibitors for reinforcement corrosion in aqueous solutions, cement grinding aids and cement quality improvement agent. Corrosion inhibitor can be used as interground additive in cement production to produce cement with more inhibiting character for steel corrosion by aggressive chloride ions. Ball milling creates fresh surfaces and these may be especially reactive. If the organic compounds bonds especially well to fresh surfaces this could affect reaction kinetics during subsequent hydration in a different way than if addition were to mix water. When lower concentrations of compounds added to the cement ball mill. This leads to an increase in surface area of the constituent/cement, and accelerate cement hydration than cement hydration if compounds add to cement as inhibitors admixtures. Based on potentiodynamic curves and EIS curves, chemical and physical methods on cement, molecular dynamic simulation and quantum chemical studies the following conclusion can be drawn: 1. All act as mixed –type inhibitor 2. The inhibition is due to adsorption of the compound molecules on the steel surface and blocking its active sites by its heteroatoms. 3. Adsorption of the investigated compounds fits a Langmuir isotherm mode. 4. Theoretical studies are consistent with experimental results.
