Fiber-reinforced concrete (FRC) is concrete containing fibrous material which increases its structural integrity. It contains short discrete fibers that are uniformly distributed and randomly oriented. ... [citation needed] Indeed, some fibers actually reduce the strength of concrete.
A test method, the pouring test, was developed for bulk measurements of these characteristics by a fast, simple, and practical procedure. Tests were made on 22 types of aggregate with six sizes of each.
Self-consolidating concrete or self-compacting concrete (commonly abbreviated to SCC) is a concrete mix which has a low yield stress, high deformability, good segregation resistance (prevents separation of particles in the mix), and moderate viscosity (necessary to ensure uniform suspension of solid particles during transportation, placement ...
Pouring concrete is a process that requires attention during every step. The final step in pouring concrete is curing. The curing process is where the concrete builds up its strength. Concrete is already wet when you begin pouring it, but it must be kept damp during the curing process.
