| Summary: | Over the centuries, concrete is commonly been used in construction world due to its
properties. From the conventional concrete until the concrete that has been diversify with
innovations, the usefulness is still the same, which is as building materials. One of the innovations
called Self-Compaction Concrete (SCC). SCC is a type of concrete that does not require any
mechanical compaction at all. This type of concrete will leveled and compacted under its selfweight.
Such concrete will accelerate the placement, reduce the labor requirements needed for
consolidation, finishing and eliminate environmental pollution. In terms of sustainability, previous
researchers have recycled so many waste in SCC for example coal ash, silica fume, hydraulic lime,
rice husk ash and fine limestone powder. Recently, recycling fly ash and bottom ash in SCC has
grasped the attention of researchers as it demonstrated promising results. Furthermore, previous
investigations already confirmed the potential of fly ash and bottom ash in replacing aggregates in
SCC represents a better option than landfill and at the same time will decrease pollution problem
especially in coal combustion area. This paper reviews the fly ash and bottom ash replacement in
SCC. |
