Quasi-Instantaneous and Long-Term Deformations of High Performance Concrete with Sealed Curing

Persson, Bertil LU (1998) In Advanced Cement Based Materials 8(1). p.1-16
Abstract
This article outlines an experimental and numerical study on quasi-instantaneous and long-term deformations of High Performance Concrete subjected to sealed curing. For this purpose more than 100 cylinders and 400 cubes were made of 8 concretes and studied in relation to creep and shrinkage, hydration, internal relative humidity and compressive strength. One heat-cured concrete was studied at temperatures other than 20°C varying between -20°C and 60°C. Analyses were carried out of quasi-instantaneous deformation, short- and long-term basic creep and autogenous shrinkage. Relationships were obtained between on the one hand, elastic modulus and creep compliance, and on the other hand, hydration, internal relative humidity and compressive... (More)
This article outlines an experimental and numerical study on quasi-instantaneous and long-term deformations of High Performance Concrete subjected to sealed curing. For this purpose more than 100 cylinders and 400 cubes were made of 8 concretes and studied in relation to creep and shrinkage, hydration, internal relative humidity and compressive strength. One heat-cured concrete was studied at temperatures other than 20°C varying between -20°C and 60°C. Analyses were carried out of quasi-instantaneous deformation, short- and long-term basic creep and autogenous shrinkage. Relationships were obtained between on the one hand, elastic modulus and creep compliance, and on the other hand, hydration, internal relative humidity and compressive strength. New and original results are presented on relationships between autogenous shrinkage and internal relative humidity. Other results confirm and validate earlier findings of normal strength concrete regarding relationships between creep compliance, porosity, compressive strength and maturity for High Performance Concrete. The project was carried out at Lund Institute of Technology between 1992 and 1996. (Less)
