Pumping Without Consolidating Concrete Construction

Concrete - Wikipedia

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined.

Self Compacting Concrete - an overview | ScienceDirect Topics

Self Compacting Concrete. Self-compacting concrete (SCC) is a special type of concrete which can be placed and consolidated under its own weight without any vibration effort due to its excellent deformability, and which at the same time is cohesive enough to be handled without segregation or bleeding. From: Construction and Building Materials, 2015

Types of Concrete Admixtures | GCP Applied Technologies

Mar 02, 2020 · Rheology modifiers – Rheology modifying admixtures increase the viscosity of the concrete while still allowing it to flow without segregation. Concrete mix designs that incorporate rheology modifiers can be used to produce self-consolidating concrete (SCC), reduce the required pressure when pumping concrete, and for underwater or anti-washout
