p ar ts ca t al ogue 25 The endbeam testing apparatus measures the early age compressive strength of institu concrete or shotcrete P ar ticularly in mining and tunneling operations it is impor tant to know the strength of material at early ages These compressive strength values cannot be obtained through traditional methods such as shooting a panel and retrieving cores because cores are difficult to extract at an early age and it is not recommended to core a shotcrete panel before a strength of 10 MP a 1450 psi has been achieved The k ey to the endbeam test method is the use of molds that can be disassembled for quick and easy extraction at any strength The test is an adaptation of the ASTM C116 Standard T est Method for Compressive Strength of Concrete Using P or tions of Beams Brok en in Flexure Minequips EndBeam T ester allows users to obtain quick easy and accurate early age strength readings for shotcrete and concrete END BEAM TESTER
