To maintain the sustainability of cement and concrete production, there is a
trend to use wastes in their production. Soda waste, generated by soda ash
production process, and beer waste, generated by beer filtration process, are
two locally produced wastes in Turkey and many other countries. The nature of
these wastes, mostly their fineness, makes them possible to be used in concrete
production, especially as a viscosity modifying agent in the self consolidating
type of concrete.
In this study, the addition of soda and beer wastes to self consolidating mortar
(SCM) and self consolidating concrete (SCC), without any treatment but drying,
and its effect on their properties were investigated. Mortar and concrete mixes
were prepared using these two wastes as cement or aggregate replacement in
various amounts. Tests like slump flow, V-Funnel and L-Box for determining the
fresh properties, and compressive strength for the hardened properties of the
mixtures were carried out to examine the effects of these wastes on the
properties of SCM and SCC.
The tests revealed that soda waste takes no role in the strength development of
the mixes. However, it is possible to use this waste as aggregate replacement to
improve the workability and flowability properties of SCM and SCC. The use of
beer waste showed contradictive results. A special treatment for this waste
before using it in concrete might be required.
