AUTOMATIC TESTING OF CEMENT STRENGTH

An automatic cement strength testing machine called the Tonicomp is described. Designed in desk form the machine automatically calculates from failure load the required strength values, mean values and standard deviations, producing a strip printout. The machine is a combination of a flexural test load frame for loads up to 10000 n and a compression test load frame for loads up to 200 kn. The two testing functions have a common control unit, an automatic measured value logging system and a minicomputer with printout facilities. Prism specimens can be tested in compression and bending to DIN, ISO and ASTM standards. The machine is also suitable for compression testing 2 in cubes and 50 x 50 mm cylinder test specimens. A test sequence of three flexural tests and six compression tests, including printout of the results, can be completed in 11 min. /TRRL/
