Water Ratio Rules and their Limitations

WATER ratio rules appear to afford a simple method of controlling the strength of concrete. It is true that the application of such rules in practice is complicated by the necessity for allowances for the absorptions of the aggregates or for the free water which may be present in them, but this may be regarded as a legitimate problem for the engineer in charge. The real difficulty lies in the fact that strength is also affected by other factors relating to the composition of the concrete, and, in the brief introductory account which follows, methods of making allowance for the effects of these factors are mentioned.
