The angularity of the aggregate can be estimated from the properties of voids in a sample of aggregate compacted in a specified manner. The angularity number ranges from zero, for a highly rounded gravel to about 11 for freshly crushed angular aggregates. Higher the angularity number, more angular and less workable is the concrete mix.

Question: Is there an accurate, quick and inexpensive way to determine the percent of water in aggregate? Answer: I batch up to 100 cubic yards of concrete a week for our inhouse projects, using all applicable admixtures. Because the water in the aggregate varies, I have to guess at the amount of water for each mix. This takes unnecessary time and extra trial batches.
