The material included within this report is the result of a series of tests of concrete specimens taken during the construction of various buildings in the cities of Pasadena and Los Angeles over a period of eight months.
The object of the problem is to determine the effect of the water ratio on the ultimate strength of the concrete as obtained from data observed and recorded from specimens taken from actual building practice rather than that from laboratory specimens made under ideal, or at least more nearly standard conditions.

The durability of concrete in sea water has been a very widely debated question from the time that disintegration of concrete in sea water first became evident. Numerous investigations and reports have been made of isolated structures in various parts of the country and from these, hasty conclusions have been reached which engineers, situated where different conditions prevail, have not been warranted in accepting. A few engineers have made investigations of a much wider scope and consequently their conclusions should be given greater weight.
