TESTING CONSTRUCTION MATERIALS WITH THE PYCNOMETER

BAUSTOFF-UNTERSUCHUNGEN MITDEM PYKNOMETER

Details are given on the use of the pycnometer in a number of tests on construction materials. The dimensions of the pycnometer and scale are a function of the characteristics of the materials tested and of the desired accuracy. Fine materials and construction materials such as cement, bitumen, sand and gravel up to a grading of 12 mm, fine asphaltic concrete, and mortar can be studied with a glass pycnometer and a scale having a capacity of 4 kg and accuracy of 0.2 g. For materials of higher grading, a pycnometer preferably made of metal with a capacity of 10 liters and accuracy of 5 g must be utilized. Results can be evaluated by means of simple calculations. The absolute density of the materials and mixed materials tested is used as a basis for the calculations. /IRRD/
