Optimum recycled concrete aggregate and micro-silica content in self-compacting concrete: Rheological, mechanical and microstructural properties

The use of additives and their proportioning in concrete to achieve better performance is one of the challenging issues in concrete technology. In this study, the influence of different percentages of recycled fine and coarse aggregates on rheological, mechanical, and microstructural properties of self-compacting concrete (SCC) is investigated. For this purpose, fine and coarse natural aggregates (FNA and CNA) were replaced with fine and coarse...
