” Danielle reassured him that people LOVED the Quack Pack. Danielle seemed embarrassed, but Shane took over the story and told it. The second time, Shane was leaning away from her in the seat, they hit a bump and she fell across his lap and as he turned away again, she accidentally head-butted him.

Since then, it has been offered as a solution to various challenges inherently associated with traditional concrete construction; i.e.

quality and speed of construction, noise pollution etc.

The advantages associated with SCC have led to the adoption of this relatively advanced technology in many contemporary projects, even before the release of specifications, testing techniques and standards that reflect the behavior of structural elements cast using high consistency concrete.

Recently, self consolidated concrete (SCC) has gained wider acceptance due its performance characteristics in the fresh state.

Light-weight Self-Compacting Concrete (LWSCC) might be the answer to the increasing construction requirements of slenderer and more heavily reinforced structural elements.

The significance of the research presented in this paper stems from the need to investigate the effect of enhanced fluidity of SCC on the structural behavior of high strength self-consolidating reinforced concrete beams.

To meet the objectives of this research, twelve reinforced concrete beams were prepared with two different generations of superplasticizers and designed to exhibit flexure, shear, or bond splitting failure.

The compared beams were identical except for the type of superplasticizer being used (second generation sulphonated-based superplasticizer or third generation polycarboxylate-based superplasticizer).

SCC flows into a uniform level under its own weight and fills in all recesses and corners of the formwork even in highly congested reinforcement areas.

However, before this special concrete is widely accepted and globally used in structures, its structural performance under different conditions should be investigated.
