Benefits and technical challenges for using self compacting concrete - Essay Example

By regulating the mix proportioning, the concrete is so formed such that it doesn’t require compaction. There is no particular code available for SCC so far even though it has started to catch wide application in modern days and again there is no definite mix proportioning procedure established (Zhu et al., 2001). In order to learn comprehensively about the feasibility of using the concepts of SCC with the available materials around, this research essay is basically grounded on the factual findings on the benefits and the critical challenges cropping up as a result of using the modern developed self-compacting concrete.

According to Loughran (2007) the basis at which SCC is highly gaining recognition, wide acceptability and increased adoption in terms of usage in modern constructions are inevitable and are essential as further illustrated in this essay. On highlights, it is of note that when large quantity of substantial reinforcement is to be positioned on a reinforced concrete (RC) member, it is never easy to certify that the formwork gets wholly filled with concrete; that is, fully compacted without honeycombs or voids.

Compaction by mechanical vibrators or by manual is very difficult in this situation. The method used of compaction, vibration, causes additional cost and delays in the projects. For underwater concreting it is always required that you use fresh concrete, which could be placed without the necessity of compaction; in such conditions vibration had been merely impossible. This challenge can now be resolved with self-compacting concrete (Persson, 2003: 374-379). The SCC flows easily around the reinforcement and into every corner of the formwork.

The SCC is very fluid and passes around obstructions to fill all the corners and nooks without the risk of either mortar or any other ingredients of concrete detaching out, and simultaneously ensuring that there are no
