Resumen

CASTANEDA VALDES, Abel  y  LI, Qi. RESEARCH PROJECT PROPOSAL: IMPACT OF THE AGGRESSIVE COASTAL ENVIRONMENT OF CUBA'S ATMOSPHERE ON THE DURABILITY OF CONSTRUCTION-MANUFACTURING MATERIALS FROM CHINA. Rev. CENIC Cienc. Quím. [online]. 2023, vol.54, pp. 96-108.  Epub 01-Sep-2023. ISSN 2221-2442.

The durability performance of construction-manufacturing materials from the People's Republic of China will be studied consideringthe impact of the aggressive coastal environment of Cuba's atmosphere.Research studies between two countries, one characterized by a very high production and commercialization of metallic materials for construction-manufacturing industry as China, and the other by present a very high impact of the aggressive coastal environment of the atmosphere on the materials as Cuba, were not found.The research studies carried out evaluated the impact of the aggressive coastal environment of the atmosphereindependently on their own materials. Thermoplastic and thermosetting polymeric materialswere not considered.The requirements by durability that are intended to be defined in the construction-manufacturing materials, will guarantee a higher long project service to all the infrastructure to be built or manufactured, mainly in any coastal zone in China and worldwide. A very significant economic benefit for developing countries is expected. In this way, the infrastructure exposed to the impact of the coastal atmospheric environment in any coastal zone worldwide, will almostnever reach its residual useful life.Cuba, as an island with a tropical coastal climate, in addition to the high relative humidity and deposition of chloride ion salts in the form of saline solution, is an ideal country to carry out these studies.A new corrosivity category of the atmosphere higher than extreme(>CX) for carbon steelin a coastal zones with high construction potentialwas reported. The corrosivity categories of the atmospherereported in China for the metallic materials most used in the construction-manufacturing industry have been lower than those determined in the tropical coastal climate of Cuba.
