National schools of art of Cubanacán. Diagnostic and restoration project of plastic arts

Abstract

This article that is presented picks up the result s of the investigations and the restoration project carried out one of the diffused works in the Cuban modern movement, the School of Plastic Arts of Cubanacán, included in the list of monuments of the World Monument Watch. The investigative work, of high scientific rigor, was executed by a multidisciplinary team that was responsible for the determination of the characteristics and quality of the materials, the dimensional risings, of the types and of the pathology, the existent microbial agents, and the forms structural employees and its behaviour. In the structural investigations different techniques were used of diagnostic. The analysis of the causes and the structural solutions leaned on in three-dimensional models and automated planes, what facilitated the interpretation and analysis of the genesis of the damages and of their solution variants. The investigation corroborated that the thermal dilation is the cause of the cracking. accompanied by the humidity like its second cause and origin of great part of the present lesions . The taken solutions are managed to allow that the structure absorb s the thermal dilations and structural movements , with out creating additional risks to the construction, as well as to clean up. to consolidate or to substitute the affected areas.
