Just as all concrete mixes should be carefully designed to achieve the required performance characteristics, properly placed and properly cured so should SCC.
Self-consolidating concrete is highly flowable, non-segregating concrete with a slump flow of 20 to 30 inches that can spread into place, fill the formwork, and encapsulate the reinforcement without any mechanical consolidation.
Its advantages are: According to ACI 237R-07, Self-Consolidating Concrete, properly proportioned and placed self-consolidating concrete can result in both economic and technological benefits for the end user.
SCC gets some its fluid quality from superplasticizers (high range water reducers), which increase fluidity without comprising the strength of the concrete.
Because high doses of superplasticizers can sometimes make concrete’s paste too thin to support the weight of the coarse aggregate, SCC usually includes viscosity modifiers as well as higher paste volume, more sand, and less coarse aggregate than traditional concrete to ensure that this does not happen. Normally SCC mixers are slightly more expensive the traditional concrete mixes.
The conference is designed to bring researchers and practitioners together to exchange the latest ideas, knowledge, and tools to build the future of concrete construction as it relates to design, construction and manufacturing of self-consolidating concrete.
The conference will take place May 15-18, 2016, in Washington D.

The ACI Foundation’s Strategic Development Council has identified self-consolidating concrete as an Industry Critical Technology.
SDC works to identify obstacles to industry adoption of self-consolidating concrete, formulates strategies to address obstacles, and determines specific tasks to execute strategies.
SCC flows more quickly from the concrete mixer as well, decreasing the time trucks spend at the job site.
Lower Costs Time is money—and reducing manpower while accelerating construction will lower costs.
SCC can accomplish this for even the most intricate architectural designs without increasing labor intensity. SCC mixes are just as strong as traditional concrete mixes and have higher early strengths.
