In this paper we wish to present the numerical model elaborated in order to simulate some physical phenomena that influence the general deterioration of steel, whether hot dip galvanized or not, in reinforced concrete. We describe the physical and mathematical models, establishing the corresponding equation system, the initial and boundary conditions. We have also presented the numeric model associated to the mathematical model and the numeric methods of discretization and solution of the differential equations system that describes the mathematical model.

A number of dibenzobicyclo[2.2.2]octane derivatives have been studied due to the interest of such compounds as ligands for
coordination compounds with potential biological activity. Their thermal behaviour has been analyzed in order to find out
more information about their fragmentation. A connection between the bridge substituents and the fragmentation process has

The influence of hot dip galvanizing on the rebar/concrete adherence was studied. The kinetics of rebars corrosion in high chlorides content concrete was studied by electrochemical methods. Unprotected (black steel) and hot dip galvanized steel were studied. The results show a mechanical resistance improvement of reinforced concrete with hot dip galvanized rebars and a better corrosion performance of hot dip galvanized steel in concrete compared to the black steel.
