Tensile deformation behaviour of self-compacting concrete under sustained loading
The deformation behaviour of self-compacting concretes of the compressive strength classes C30/37, C45/55 and C60/75 under sustained tensile loading was investigated up to 2.5 years. The long-term tensile strength was estimated to be 69% of the short-term tensile strength, determined at an age of 28 days. Load-free shrinkage has been measured. The usual way to determine creep is to subtract the measured shrinkage strain and the initial strain from the measured total strain. In doing so, a phenomenon was discovered which is called stressinduced shrinkage. It seemed that the stress-induced shrinkage tends to increase with decreasing compressive strength.
