What Is Self-Compacting Concrete And What Kind Of Material Is Used For It?
Self-compacting concrete (SCC) is a unique kind of concrete that, because of its exceptional deformability, can be laid and consolidated under its own weight without the need for vibration exertion. At the same time, it is cohesive enough to handle without bleeding or segregation. Superplasticizers and stabilisers are used to greatly improve the flow rate and ease. Without separating the coarse aggregate, it compacts into every section of the mould or formwork with just its own weight. In this post, we are going to discuss what exactly it is and what kind of material is used for it. Let's read it out: Cement You can use either 43- or 53-grade ordinary Portland cement. Aggregates A maximum of 20 mm in size can be used for aggregates in SCC design. The aggregate size that is used might be between 10 and 12 mm if the reinforcement that is being used for the construction is crowded. The ideal option is to use well-graded aggregates in either a round or cubic form. Natural aggregates o...
