PATOLOGIAS DO CONCRETO FRESCO EM AMBIENTES DE TEMPERATURA ELEVADA

Abstract

Civil engineering adopted the concrete as
the structural element most commonly used in
construction, the result of the mixture of heterogeneous
components chemically reacting to the added water.
The final product only acquires resistance provided in
the design of the quality of material is checked, if the
dosages are met, the implementation is careful, and
curing conditions are met. Specifically in the latter
item, there was a negative contribution to its realization
in ideal conditions: it is the increase in temperature
from global warming. Since the hydration exothermic
reactions, and while the concrete during the curing
period exposed to an environment that contributes to
the loss of surface water, disease can appear in
structures, such as shrinkage, porosity and
carbonation. If not taken into account the expected
temperature rise in the near future there may be
structural elements with lower resistance and service
life.
