Recycled-concrete Aggregate Generally Has A Higher Absorption And A Lower Specific PPT. Presentation Summary Recycled-concrete aggregate generally has a higher absorption and a lower specific gravity than conventional aggregate. Absorption values typically range from
assumes an aggregate bulk specific gravity of 2.65. If the specific gravity is outside of the range of 2.55 and 2.75, the amounts of aggregate shown in the table should be multiplied by the ratio of actual bulk specific gravity to 2.65. In addition, the table shows ranges of aggregate gradation and rates of materials. If the aggregate has a ...

When you dealing with specific gravity you are using it to calculate absolute volumes ..Do not confuse with Bulk Volumes An Example 1 Cement bulk volume 94 lbs cubic foot 2 Cement absolute volume 196.56 lbs cubic foot 3.15 x 62.4. Everything in mix designs is absolute. Absolute volume accounts for all void spaces being filled.
