Production of self-compacting concrete using limestone powder

Although there are visible signs of its gradual acceptance in North Africa through its limited use in construction, Libya has yet to explore the feasibility and applicability of self-compacting concrete (SCC) in new construction. The current study revolves around SCC made of locally available materials and the harsh environmental conditions. This paper deals with the investigation into the effect of the water to powder ratio and limestone powder (LSP) on the fresh and hardened properties of SCC.

Self-compacting concrete (SCC) is a type of concrete that is produced without compaction effort in the formwork. It settles by its own weight without any bleeding and segregation and behaves cohesively enough [1]. The use of SCC is believed to provide various advantages such as reduced construction time, labour costs and noise pollution as well as the easy filling of congested and thin sections. SCC is a desirable achievement in the construction industry for overcoming the problems associated with cast-in-situ concrete. Also it can be pumped over longer distances due to its high fluidity and...
