| 摘要： | The first objective was to determine if test results would be repeated from batch to batch when the mix proportions for each batch are the same. At the same time a comparison between sulfur capped cylinders and neoprene capped cylinders would be made. The next objective was to determine if the compressive strength and workability of a mix changes when the relative amount of coarse aggregate and sand is changed. Finally, the authors wished to determine if changing the maximum coarse aggregate size in a mix from 1 1/2 inch to 3/4 inch will affect its compressive strength. |
