Shrinkage Behavior Of Self-compacting Concrete |

In the structures where long-term behavior should be monitored and controlled, creep and shrinkage effects have to be included precisely in the analysis and design procedures. Shrinkage varies with the constituent and mixture proportions, and depends on the curing conditions and the work environment as well. Self-compacting concrete SCC contains combinations of various components, such as ...

Self-consolidating Concrete Topic

2020-4-1Self-consolidating concrete SCC is highly flowable, nonsegregating concrete that can spread into place, fill the formwork, and encapsulate the reinforcement without any mechanical consolidation. In general, SCC is concrete made with conventional concrete materials and, in some cases, with a viscosity-modifying admixture VMA. SCC has also been described as self-compacting concrete, self ...
