In order to have a basis for comparison of the various tests,auxiliary specimens were made from each batch of concrete S X 13-in. cylinder and three S~in. cubes v:ere made from themiddle of each batch. Ylhen two specimens were made from onebatch, one cylinder and one set of cubes were made to controlboth specimens.
