We review our field investigations of construction materials which were initiated after the 1985 Mexico City earthquakes. We report observations on reinforcing steel samples collected in the ruins of collapsed buildings and describe the experiences in the production and testing of HSLA steel reinforcing bars with mechanical and metallurgical properties suitable for earthquake resistant construction. We review some aspects of the cement and concrete industries of Mexico before 1985 and present a description of the properties of polymer modified cements considering the potential not only for construction but for many other applications.
