This study is based on a remolding test which measures the relative effort required to change a mass of fresh concrete from one definite shape to another by igging. It was found that workability depends on three main or factors: ( I ) proportion of cement-water paste, including paste (3) admixtures, if any; (2) consistency of the gradation and type of aggregate. A wide range in coarse aggregate gradations can be used with equal cement economy, provided that with each graduation the optimum percentage of sand and pea-gravel is used.
