Mortero impermeable a base de plástico reciclado PET para revestimientos de edificaciones de la ciudad de Zamora

Abstract

The present investigation proposes a solution that minimizes the causes for the damage in coatings or plastering of buildings of subtropical climate, as it is the case of the city of Zamora, in the province of Zamora Chinchipe, South East of Ecuador, characterized by high pluviometric level, and approximately 90% relative humidity. This last characteristic of the climate, the rainwater that filters through the subsoil, causes pathological problems in the coatings of not less than 60% of existing constructions, that is why the lower part of internal plasters is progressively deteriorating. in facades, as well as diminishing the environmental quality inside the homes. Identified the problem is the experimentation, work that begins by studying the mortars that is the material of 99% in the plastering of buildings. The mixture is analyzed with sand and cement, which will serve as a base or standard for adding polyethylene terephthalate (PET) particles, in order to improve its impermeability while maintaining the physical-mechanical characteristics that national and international standards require. The comparison was developed with mixtures containing 0%, 5%, 10% and 20% PET in the mixture in replacement of the aggregate.
