Abstract:
The workability of a concrete is that property which is indicated by the effort required to place the concrete in order to obtain a uniform and homogeneous finished product. This property was so defined by Messrs. Pearson and Hitchcock, Talbot and Richart, and other investigators. (Ref. 1, 2, 7, 8, 9, 10, 11, 12, 13.) Because workability is the resultant of several properties of the ingredients and not a simple physical property it is di5- cult of precise definition and measurement. It is affected by the proportions of the mix, the type and gradation of the aggregates, the cement and admixtures used, the quantity of mixing water, and possibly by other variables.
