Review ofudSustainability in Self Compacting Concrete: the use of waste and mineral additives asudsupplementary cementitious material and aggregate.

摘要

Concrete is one of the commonly used construction materials, but there is a need to develop a newudand sustainable technology to make concrete more affordable. With the advancement inudtechnology, concrete was no longer seen as a three entity (binder, aggregate, and water). Theudunique workability properties of SCC make it unique in the concrete industry. This review assessedudthe materials, strength, rheological properties of agricultural waste, industrial waste and mineraludadditives in SCC production. The effect of the utilization of these additives and replacements onudstructural, mechanical and rheological properties of SCC was espoused. The review revealed thatudthe use of both industrial and agricultural waste enhances the strength properties of SCC.udAdditionally, the use of agricultural waste improves the rheological properties of fresh concrete.udThe utilization of expansive material should be discouraged in SCC production. The reviewudrevealed that SCC developments ensure a good balance between deformability and stability. It wasudtherefore recommended that SCC should be utilized in pavement construction, particularly whenudhigh axle load is expected.
