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.
