101040310104011010308 Dimensional StabilityPreviewConcrete shows elastic as well as inelastic strains on loading, and shrinkage strains on drying or cooling. When restrained, shrinkage strains result in complex stress patterns that often lead to cracking.In this chapter, causes of nonlinearity in the stress-strain relation of concrete are discussed, and different types of elastic moduli and the methods of determining them are described. Explanations are provided as to why and how the aggregate, the cement paste, the interfacial transition zone, and the testing parameters affect the modulus of elasticity.
