As SCC concrete undergoes self-compaction by its own weight, it has to attain adequate filling ability so that the mix reaches every area. Friction between the aggregates restricts this spreading and hence the filling ability. This issue is solved by increasing the paste content in SCC mix ...

Influence of Mineral Admixtures on Self Compacting Concrete
WebThe authors report that self-compacting concrete was first developed in 1988 to achieve durable concrete structures and since then, various investigations have been carried out and this type of concrete has been used in practical structures in Japan, in order to shorten the construction period by large-scale constructions, such as, the ... WebApr 8, 2024 · In self-levelling concrete, reduction in w/c ratio or cement content is not considered. 2. Self compacting concrete. Similar to self leveling concrete, self-compacting concrete also focuses on high slump without segregation/bleeding so that concrete can be placed in heavily reinforced sections. 3.
