Specificity of Deformation and Strength Behavior of Massive Elements of Concrete Structures in a Medium with Low Humidity

Specificity of Deformation and Strength Behavior of Massive Elements of Concrete Structures in a Medium with Low Humidity discusses the influence of weather conditions, the density of the structure, and how these elements, along with others, affect the concrete curing process. It explores the effects of climate in all phases of construction, its impact on the rheological properties of concretes, and the carrying capacity of compressed concrete and reinforced concrete elements. In addition, it provides the methods to determine the basic heterogeneity of mechanical properties of concrete structures and novel calculation methods for concrete columns and reinforced concrete beams.
