What reading level is The Strength of Fine Aggregate Concrete book?
To quickly assess the difficulty of the text, read a short excerpt:
It is evident from this diagram that to obtain an ultimate strength at 28 days of 3000 pounds per square inch, for example, 7. 5 sacks of cement must be used, per cubic yard of concrete if the aggregate is graded up to one-eighth inch, and 6. 1, 4. 8, and 4. 6 sacks per yard if the aggregate is graded up to one-fourth, three-eighths, and one-half inch, respectively. Comparing the results obtained for the 8-sack mix, for example, we find strengths of 3300, 4400, 5700, and 6000 pounds per square ...inch when the aggregate is graded up to one-eighth, one-fourth, three-eighths, and one-half inch, respectively. The lower diagram of Figure 4 was derived from the upper diagram by reading from the curves, for a given cement content, the strengths obtained for the several sizes of aggregates. These values were then plotted against the corresponding sizes of the aggregate. From this diagram it is evident that, up to a certain point, for a given quantity of cement a stronger concrete will be obtained for the coarser material than for the finer aggregate.
