Good concrete control methods require testing concrete in the finished structure as well as the usual specimens made at the time of placing. Four-teen methods of testing concrete in the finished structure are described, half of them requiring pre-iminary measures when placing the concrete. These tests are much more cumbersome than the other half which may be performed any time at any point. It is suggested that both types be used together.
