Mechanical Properties of Self-Compacting Concrete
Self-compacting concrete (SCC) , also known as self-consolidating concrete
, was developed in the late 1980’s, although earlier ‘look-alikes’ surely exist,
though not defined as such. In comparison with conventional concrete, referred to
in this report as vibrated concrete (VC), SCC can be considered on the one hand as
a new type of high-performance material of a different approach to mix design and
rheological characteristics. On the other hand, SCC can be seen as a new approach
to casting concrete enabled by adjusted fresh concrete properties. In reality, SCC is
a combination of both approaches that has enabled to push the boundaries of
concrete technology to a new area.
Several methods exist for the mix design of SCC, as explained in [3]. In various
parts of the world, different concepts might be followed for the proportioning of
SCC and are referred to as ‘powder-type SCC’, ‘VMA-type SCC’, or ‘mixed-type
SCC’.

self-compacting concrete (SCC) has been applied in the
construction industry. In this period, a lot of research has been performed with
regards to the applicability, mix design, pump-ability, durability, rheology, etc. of
SCC. In the nineties, little attention was devoted to the mechanical properties of
the material and to its structural performance. Recently, an increasing amount of
research has been dedicated to these mechanical properties of SCC [1].
Research projects often include data on compressive strength, tensile strength,
and Young’s modulus, although the main focus remained on other aspects of the
concrete as mentioned above. In the past, some authors, e.g. Domone [2] and
Holschmacher [3], have presented surveys on the mechanical properties of SCC
based on available literature. Due to a scarce amount of available test results, these
studies were based on a limited set of data.
