  • (17) After curing of the cement in a environment of 37 degrees C the resulting cement rod was released from the cylinder and the diameter of the rod was measured at 37 degrees C. The influence of the "foaming effect" on the transverse dimensions of the rods was studied by curing the cement at 37 degrees C and 2 atm air pressure in a high-pressure-vessel.

Tympan


Definition:

  • (n.) A drum.
  • (n.) A panel; a tympanum.
  • (n.) A frame covered with parchment or cloth, on which the blank sheets are put, in order to be laid on the form to be impressed.
