Abstract
This paper presents observations made on the use of self-compacting
concrete for pre-cast elements at Byggebjerg Beton A/S during the
last 3 years. The elements include L- and sandwich elements and are
mainly produced for agriculture purposes. In general, the flow properties
and air content are very sensitive to small variations in temperature,
aggregate size distribution, and moisture content. For instance,
the air content seems to decrease as the temperature increases. For
vertical form filling applications it is important to adjust the filling
technique according to the properties of the concrete to achieve a
good surface quality with a limited number of blowholes. For horizontal
castings it is important to keep the concrete flowing to avoid
casting joints. Blocking is avoided by using the right type of spacers
and a maximum size aggregate of 8mm. However, if the concrete has
to flow over longer distances blocking may become a problem.
