Abstract
Present paper describes some aspects of the restoration project recently undertaken in La Zarzuela Racecourse, designed by E. Torroja and Dominguez in 1934. Despite the good mechanical work of steel, it has started a deterioration process which has caused the corrosion of reinforcement by carbonation. It has been detected corrosion attack in some places due the breaking of the upper waterproofing membrane of the shell which enabled the water to remain long periods in the roof and therefore promoted corrosion of reinforcement. For the repair first an assessment of the degree of corrosion was made. The restoration project finally consisted in the injection of all the cracks in order to assure the joint work of the shell and the patching of the deteriorated zones. Profiting these works it was installed a monitoring system of corrosion sensors. Results of the recording are given in the paper.
