Resumen

BUSARI, Ayobami A.; AKINMUSURU, Joseph O.  y  DAHUNSI, Bamidele I.. Review of Sustainability in Self-compacting Concrete: the Use of Waste and Mineral Additives as Supplementary Cementitious Materials and Aggregates. Port. Electrochim. Acta [online]. 2018, vol.36, n.3, pp.147-162. ISSN 0872-1904.  https://doi.org/10.4152/pea.201803147.

Concrete is one of the most commonly used construction materials, but there is a need to develop a new and sustainable technology to make it more affordable. With the advancement in technology, concrete is no longer seen as a composite of three elements (binder, aggregate, and water). The distinctive workability properties of SCC make it unique in the concrete industry. This review has assessed the materials, strength and rheological properties of agricultural waste, industrial waste and mineral additives in SCC production. The effect of the utilization of these additives and replacements on structural, mechanical and rheological properties of SCC has been studied. This review has revealed that the use of both industrial and agricultural waste enhances the strength properties of SCC. Additionally, the use of agricultural waste improves the rheological properties of fresh concrete. The utilization of expansive materials should be discouraged in SCC production. This review has revealed that SCC developments ensure a good balance between deformability and stability. It is therefore recommended that SCC is utilized in pavement construction, particularly when high axle load is expected.

Palabras clave : Self-compacting concrete; mineral additives; agricultural waste; structural properties; rheology.
