Concrete curing analysis for high durability of structural concrete
-
Descrição
-
Concrete is the second material most consumed in the world, losing only to water, and currently its
consumption is in the order of 19 billion tons per year. Concrete has been widely used for its versatility,
durability and performance. Specifically in concrete, techniques are sought to reduce its permeability,
since this provides greater mechanical strength and durability. For this, it is necessary to use specific
additives for waterproofing by integral crystallization, which are added to the concrete trace at the time of
its production. However, the objective of this article is to analyze the self-healing concrete for the
durability of the structural concrete according to NBR 9575. In this way the research method used was
constituted by a case study that demonstrates the importance of the process of crystallization of the
concrete in the waterproofing system and the role of the technological rationalization process to which the
construction industry was driven by factors such as the increase in the demand for buildings, be they
residential, commercial or structural works in the cities. The results showed that the body with
incorporated additive showed approximately 13% more resistance, the observation made to the naked eye
and, the rupture was less sinuous than in the body of the simple trait, this suggests a more resistant
cementitious paste after the addition of the crystallizing.
Keywords: Concrete, Self-healing, Crystallizing.
