ABSTRACT
This chapter deals with the role of žbers in extending the cracking resistance of concrete subjected to drying shrinkage. In hot and low-humidity environments, concrete shrinks due to loss of moisture from capillary and gel pore microstructure. When concrete is restrained from free shrinkage, tensile stresses develop and may result in cracking if the stress exceeds materials’ low tensile strength. This is more dominant when at an early age the tensile strength is quite low and rate of moisture evaporation is high. The main objective of this chapter is to study effect of žbers on responses of a well-known restrained shrinkage test.
