Abstract
This paper presents the properties of hardened self-compacting concrete (SCC) and compare them to those reported for normally vibrated concrete (NVC). The mechanical properties evaluated are: compressive strength, modulus of elasticity, tensile strength, creep, shrinkage and bond with reinforcement. The very wide range of materials and mixes already used for SCC produced a significant scatter of data, but clear conclusions have been obtained. The compressive strength of SCC was likely to be the same or greater than that of NVC by using the same content of cement and water. Modulus of elasticity of SCC was lower than that of NVC of the same compression strength. Hardened SCC tended to have a tensile strength the same or better than that of NVC. The magnitude of creep was shown to be the same as for vibrated concrete. Shrinkage of SCC was of magnitude entirely comparable with that of NVC. The bond of SCC to embedded reinforcing and prestressing steel tended to produce a slightly better performance than NVC. The conclusions provide full confidence in hardened SCC reaching the required engineering properties.
