Abstract:
An experimental study of various mix proportions for heavy cnncrete is described and a proportioning procedure for concrete of given strength and density is explained. The primary object of the investigation was to determine a procedure for the improved proportioning of mixes using steel punchings as coarse aggregate with steel shot of varying size as fine aggregate. First, the individual ingredients were investigated, then, the optimum mixture. Various heavy concrete mixes were made and strength tested at 7, 14, and 21 days. Tests results are interesting in that they indicate a possible conclusion that the strength of this concrete is proportional to its density the water-cement ratio being only one of the factors involved in determining the density. This suggests the generalization that, in the plastic range, the strength of any concrete of given ingredients is proportional to its density.
