Basic Deformations of High-Performance Concrete at Early Ages.
(1997) In Nordic Concrete Research 20. p.59-74- Abstract
- Creep and shrinkage are two major problems to be discussed in concrete design. Basic creep is studied during constant loading, temperature and moisture conditions, i.e. no exchange of moisture takes place to or from the specimen during the test period. In this paper an experimental and numerical study of basic creep of High Performance Concrete (HPC) is outlined. For this purpose cylinders and cubes were cast. Quasi-instantaneous deformation and basic creep including autogenous shrinkage were observed over 3 years. Analysis's of elastic modulus, early creep and long-term creep including autogenous shrinkage are presented. HPC autogenous shrinkage had a great influence on the results. The autogenous shrinkage in its turn is caused by the... (More)

The autogenous shrinkage in its turn is caused by the self-desiccation of HPC. The study was carried out in 1992 through 1994 at Lund Institute of Technology, Division of Building Materials, Lund, Sweden. (Less)
