Análisis de la exhalación de gas radón-222 en mampuestos de hormigón de la provincia de Tungurahua y su incidencia en la construcción

Abstract

The study of the behavior of constructive elements in buildings is continuously developed to provide parameters that support new innovations in the engineering world and specify reliable, safe and comfortable forms in future constructions. For the preparation of this project, physical tests were carried out on representative samples from zone 3, which includes the provinces of Cotopaxi, Tungurahua and Pastaza. In the particular case of the province of Tungurahua, which has 92 concrete block distributors, the results obtained from these analyses show a resistance below the limit established in the NEC. The results obtained show that the elaboration process and the quality of the raw material used in the construction of blocks are the fundamental basis for their best response to the agents that could affect their structural behavior; therefore, the readjustment of the dosage of each component of this element should be considered, since they do not reach the allowed values individually, even in an average of 3 samples tested from the same elaboration batch. Satisfactorily, the elements studied in this research do not exhale the minimum amount of Radon-222 gas (100 Bequerelio per cubic meter), which is considered the third cause of lung cancer in the world. A characteristic cadaster of the block distributors in the Province of Tungurahua was carried out, which allowed us to collaborate with a better identification of the most critical points.
