Reports results of strength and expansion tests on three series of concrete specimens begun in 1910, in 1923, and in 1937. More than 2500 concrete cylinders and a still larger number of mortar briquets and cylinders were made for these test programs. Most of the specimens were cured outdoors; some were cured under water, and others in the laboratory. Variables in types of cement, types of coarse aggregate, consistency, and methods of placement are in- cluded in these experiments.
