In order to proffer solution to the difficulties experienced in achieving a super-workable concrete commonly known as Self Compacting Concrete, four mixture design methods were carefully selected and investigated. Three mixes were designed for each method considered in accordance with their specifications. The methods considered are: the American Concrete Institute, EFNARC, European Project Group and the Optimal Mixture Design (Yu et al) methods. The results disclosed that the EFNARC method is the most reliable method in the production of super-workable concrete as it significantly satisfies the fresh properties of the concrete.

Keywords : Mix Design Methods, Super-Workable Concrete and Fresh Properties.
