:: Self Consolidating High Performance Concrete :: SCC

Self-Consolidating ConcreteDelivers Efficiency, Beauty, Savings and More. Self-consolidating concrete, also known as self-compacting concrete (SCC), is a highly flowable, non-segregating concrete that spreads into place, fills formwork, and encapsulates even the most congested reinforcement, all without any mechanical vibration.

Numerical simulation of formwork pressure while pumping

Jul 01, 2014 · Self-compacting concrete (SCC) enables new casting techniques, filling formworks by pumping bottom-up. However, fundamental questions remain concerning the formwork pressure when following this advanced filling procedure.

Similarities and Differences of Pumping Conventional and

Similarities and Differences of Pumping Conventional and Self-Compacting Concrete 3 Figure 1. Short pumping circuit (25 m). Testing procedure As the volume of concrete required for the pumping tests was 1.5 and 3.25 m3 for the short and long circuits, respectively, the concrete was prepared in a ready-mix

CONCRETE 101

Slump is a measure of concrete consistency or fluidity. Consistency is the ability of freshly mixed concrete to flow. For given proportions of cement and aggregates (without admixtures), the higher the slump, the wetter the mix. Four-inch (4") slump is very common with normal weight concrete and is a good average slump for pumping.

GranitFlow - Granitmix - Self Compacting Concrete

Self Compacting Concrete. New to Granitmix is Granitflow, a high performance self compacting concrete, normally used for floor slabs which can be placed quicker and easier than conventional concrete resulting in reduced labour costs. Reduced labour – due to the ease of placement, large pour sizes are achievable with reduced labour and plant

Self Compacting Concrete (SCC) - Advantages And Disadvantages

Parameters influencing pressure during pumping of self

Pumpability of Self Consolidating Concrete Abstract During field trials, involving pumping of self compacting concrete, changes in rheological properties have been observed. In order to predict possible changes, studies were undertaken on self compacting mortar (SCM) where various mixing as well as pumping intensities were applied.

BENEFITS The superior self-compacting concrete Northfield Construction Ltd Loughborough University A large retaining wall was required of between 4.5m and 4.9m. The client and

Experimental study and application of manufactured sand

However, the effect of structural design measures and construction methods finally depends on the preparation of concrete. Micro-expansive self-compacting concrete (SCC) is the optimum selection to ensure the compactness of the filled concrete in the steel tube and the good ferrule effect between the steel tube and the confined concrete,,,, .

Understanding the pumping of conventional vibrated and

Jan 01, 2012 · Estimated velocity profile during pumping of conventional vibrated concrete (CVC, top) and self-compacting concrete (SCC, bottom), showing that the bulk SCC is sheared while CVC is not. Highly workable concretes, and especially self-compacting concrete (SCC), have a low yield stress, possibly inducing shearing of the concrete itself.

Rheology and pumping of self-compacting concrete

Self-compacting concrete is a very flowable cementitious material, which does not need external vibration during casting. On the other hand, somewhat surprisingly, pumping of self-compacting concrete requires higher pumping pressures than traditional concrete. This paradox can be fundamentally explained by studying the rheological properties of self-compacting concrete and linking them to

Self Compacting Concrete (SCC) | Non Segregating Concrete
