Practical Evaluation of Using Lightweight Self-Compacting Concrete in Reinforced Concrete Constructions

Self-compacting concrete or SCC can be considered as the concrete of the future. The most important feature of self-compacting concrete is flowing under its own weight to fill the mould or framework completely, and also to create a dense and sufficiently homogeneous mix between the bars, without any...
