Compressive Creep of a Lightweight, High Strength Concrete Mixture
… time dependent, inelastic deformation called creep. Creep without moisture loss is referred to as basic creep and with moisture loss is referred to as drying creep. Shrinkage is the combination of autogeneous, drying, and carbonation shrinkage. The combination of creep, shrinkage, and elastic …

Compressive Creep of Prestressed Concrete Mixtures With and Without Mineral Admixtures
… and a slow inelastic deformation called creep. Creep of concrete is composed of two components, basic creep, or deformation under load without moisture loss and drying creep, or deformation under drying conditions only. Deformation of concrete in the absence of applied load is often …

Investigation of Concrete Mixtures to Reduce Differential Shrinkage Cracking in Composite Bridges
… shrinkage by decreasing shrinkage and increasing creep. . In addition, the amount of tensile creep that concrete experiences under long-term tensile stresses were quantified and compared to compressive creep values in order to gain a better understanding of how concrete behaves under tension. Test …

Early age creep and shrinkage of emerging concrete materials
… cracking. Early age properties, such as tensile creep, are not well understood and the availability of literature on the subject is limited. The goal of this research is to improve the understanding of early age behavior in emerging materials in order to improve long term durability. The early …

Analysis of Hot Mix Asphalt (HMA) Linear Viscoelastic and Bimodular Properties Using Uniaxial Compression and Indirect Tension (IDT) Tests
… obtained from either the uniaxial or triaxial compressive dynamic modulus test. Furthermore, as part of the performance-based mix design process, the triaxial dynamic modulus has been selected to predict rutting and fatigue cracking, and the Indirect Tension (IDT) creep compliance test to …

Characterization of Thermophotovoltaics and Materials for High-Temperature Thermal Energy Storage
… part of this thesis, we address the challenge of creep in graphite components in the TEGS system. We characterize compressive creep rates in graphite insulation and propose mitigation strategies.

Viscoelastic behavior of water-blown flexible polyurethane foams
… compression load relaxation, and compression creep, were utilized to evaluate the behavior of these materials at constant temperature and/or relative humidity, RH. The tensile stress relaxation tests were performed at a 25 percent strain level. The majority of the compression load relaxation …
