Assessment of factors influencing the development of drying shrinkage in concretes produced in Cuba

Cracking of concrete elements resulting from drying shrinkage is a phenomenon that affects a large number of structures built with this material worldwide. As a consequence, the buildings are not only affected aesthetically, but also structurally, since cracking patterns, in addition to affecting th...

description	Cracking of concrete elements resulting from drying shrinkage is a phenomenon that affects a large number of structures built with this material worldwide. As a consequence, the buildings are not only affected aesthetically, but also structurally, since cracking patterns, in addition to affecting the element initial stiffness, acts as a pathway for atmospheric agents, contributing to the development of corrosion in reinforcing steel and, consequently, affects durability. This paper presents a characterization of the processes of development of strains due to the shrinkage in a set of representative samples of Cuban concretes.

Results prove the relevance of the formation and composition of the microstructure and the coarse aggregate influence in shrinkage development. Effectiveness of tensile-active shrinkage reducing additives is assessed, among other solutions, resulting in the most effective mitigation strategy.
