It has become a research hotspot to explore raw material substitutes of concrete. is important the mechanical properties self-compacting concrete (SCC) with slag powder (SP) and rubber particle (RP) replacing cement coarse aggregate, respectively. 12 kinds composite modified (CMSCC) specimens were prepared by using 10%, 20% 30% SP 30%, 40%, 50% 60% RP. The rheological properties, microstructure...

self-compacting concrete (scc) is a highly fluid yet stable concrete that can flow consistently under its own weight, pass between bars, and fill in formwork without the need of compaction. the application of scc effectively resolves the difficulties of concreting in situations with complicated formwork and congested reinforcements. in this paper, the bond between scc and steel reinforcement wa...

The utilization of recycled aggregates and various industrial by-products is considered a sustainable strategy in the concrete industry. In this study, effect maximum size coarse aggregate cementitious binder content on fresh hardened properties self-compacting was investigated. Self-compacting concretes with sizes 9.5 mm, 12.5 19 mm were prepared at water-to-binder ratios 0.39, 0.42, 0.45, res...
