Slenderness limit for reinforced ultra-high-performance concrete
The use of ultra-high-performance concrete (UHPC) allows for much smaller cross-sections compared to conventional reinforced concrete columns, which may make reinforced UHPC (R-UHPC) columns more susceptible to slenderness effects. Currently, there is no guideline in design standards for the slenderness limit of R-UHPC …

Applications of Cement
Self-consolidating concrete is a high-performance concrete that can flow easily into tight and constricted spaces without segregating or requiring vibration. The key to creating SCC, also referred to as self-compacting, self-leveling, or self-placing concrete, is a mixture that is fluid but also stable, to prevent segregation.
