The spread (slump flow) of SCC typically ranges from 18 to 32 inches (455 to 810 mm) depending on the requirements for the project.
High Performance Concrete (HPC) refers to concrete with a specified compressive strength of 6,000 psi and greater.
By carrying loads more efficiently than normal-strength concrete, high-strength concrete can reduce the total amount of material placed and lowers the overall cost of the structure.

of Hydraulic Cement Mortars (Using 2-in.SCC is an increasingly attractive choice for optimizing site manpower (through reduction of labor and possibly skill level), lowering noise levels, and allowing for a safer working environment.SCC allows easier pumping (even from bottom up), flows into complex shapes, transitions through inaccessible spots, and minimizes voids around embedded items to produce a high degree of homogeneity and uniformity.If needed, low dosages of viscosity modifier can eliminate unwanted bleeding and segregation.Since its inception in the 1980s, the use of SCC has grown tremendously.Lightweight concrete for structural applications has a density of 90-115 lb/ft³ compared to normal weight concrete of 140 – 150 lb/ft³.
