Self-compacting concrete is a fluid mixture suitable for placement in structures with congested reinforcement without vibration. The development of self-compacting concrete must ensure a good balance between deformability and stability. In addition, the compactibility is affected by the characteristics of the materials and the proportions of the mixture; it becomes necessary to develop a procedure for SCC blend design.
Self Compacting Concrete has to be designed and tested before it is produced and used for construction. During the SCC evaluation, local materials and equipment must be tested to find the appropriate proportions of the concrete mix and the appropriate mixing times for the element to be molded. Different types of fillers can result in different strengths, shrinkage and drag, but shrinkage and creep will generally not be higher than for traditional vibrated concrete.
The following figure shows a flowchart describing the procedure for the design of the SCC mix:
