Traditional building technique of military architecture in Veracruz, Mexico and Cartagena de Indias, Colombia for conservation

Military architecture is a cultural heritage that emerged and developed between the sixteenth and nineteenth centuries, with economic - commercial purpose, in a place that was known as the New World. The fortifications had the role of ensuring the stability of colonial trade and protect malls port smuggling, privateering and piracy, which is exercised through the sea. During this period many fortifications, military representative of classical modern architecture were built. Permanent bastioned fortresses were the most relevant. Their building codes reflect the principles of the Italian Renaissance, dominating the ideal of perfection, the perfect and shapely traces, geometric, harmonic, balanced, monumental and functional. These forts functioned as main bastions of cities, which are communicated interact with other complementary works as military strongholds, coastal batteries and campaign platforms, towers, ramparts, trenches and magazines, establishing a maritime defense system and campaign. This culminated in military device walls of earth and sea, which became commercial cities in solid strongholds. In this paper the original technique for processing old for the conservation and restoration of the fortifications of San Juan de Ulua in Veracruz, Mexico and San Fernando de Bocachica in Cartagena de Indias, Colombia supplies were investigated. The analysis of the materials used in its construction, has the purpose to determine its composition. Considering the problems presented landmarks, just point out the results of the analyzes carried out by the analytical techniques of X-ray diffraction and scanning electron microscopy, experienced the stone material used in construction, give us important information propose specific treatments for preservation.
