Description:Excerpt from Pouring and Pressure Tests of ConcreteThe results of this test are Shown in Fig. 4. On these diagrams the ordinates represent the head of concrete on the pressure cell and the measured pressure of the concrete against the form. The abscissas represent the time in minutes elapsing after the surface of the concrete was at the level of the pressure cell. In every case the first reading on the cell was taken from 5 to 10 minutes after the concrete had come into contact with the cell.From the curve shown for cell No. 1, itwill be noted that as the head of concrete increased, the pressure also increased almost uniformly up to the maximum observed pressure. However, 30 minutes after the initial reading-had been taken, or approximately 35 to 40 minutes after the concrete had reached the level of the cell, the pressure began to decrease in spite of the increasing head of concrete on the cell. Apparently this decrease was because the concrete which was in contact with the cell had begun to harden, causing it to act more in the nature of a solid than of a liquid. Cell No. 1 registered zero pressure about 150 minutes after the initial reading.About the PublisherThis book is a reproduction of an important historical work.
