Abstract
The effect of meteorological variables such as relative humidity, maximum temperature, and predominant wind orientation, as well as oxidant species on the variation of mechanical resistance to compression of the cylinders extracted from two electric transmission towers was investigated. The obtained results are compared with the mechanical strength to compression achieved in concrete cylinders prepared in the laboratory and submerged in solutions of nitric acid and sulfuric acid in concentrations taken from the statistical data of nitrous oxide and sulfurous present in the environment where have installed the towers under study. The results show a decrease in the mechanical strength of the exposed cores in the predominant direction of the wind and of the cylinders submerged in the solution with acids, concluding that both conditions favor the degradation of concrete properties.
