Consolidating Concrete in Congested Areas Concrete Construction Magazine

Mar 01, 1994  Consolidating Concrete in Congested Areas. Some design requirements for concrete construction, such as seismic post-tensioning, can result in congested areas within the formwork that are difficult to consolidate. Reinforcing steel, embedments, boxouts, prestress ducts, and anchorages all contribute to congestion.

Self Consolidating Concrete - Overview of SCC

Concrete that segregates loses strength and results in honeycombed areas next to the formwork. It is the self-consolidating nature of SCC that makes it so valuable in construction. SCC can flow into very intricate forms or forms that

consolidation of concrete Topic

Nov 01, 2021  Consolidation is the process of inducing a closer arrangement of the solid particles in freshly mixed concrete or mortar during placement by the reduction of voids, usually by vibration, centrifugation, rodding, tamping, or some combinations of these actions. Consolidation is needed because a mass of freshly placed concrete is usually honeycombed with entrapped
