The method of care contributes to the change of the concrete structure, and as a result, its properties change.
The article presents the impact of three different ways of care on concrete properties. This study considers
the results of three different approaches to care on concrete properties. The study looks at the effects of the
concrete care methods on compressive strength, chloride penetration into concrete, carbonation and water
absorption, and sorptivity tests were carried out. On the basis of the performed tests, it can be concluded that
the care of concrete in conditions of low humidity at the level of 53% causes a significant deterioration of the
concrete properties.
