FLEXURE TESTING MACHINE (HAND OPERATED)IS : 516 BS 1881, ASTM C 78.
Flexural tests of concrete beam have their own importance in concrete Road Constructions as well as Buildings constructions. Normally concrete beams of sizes 10cm x 10cm x 50 cm or 15cm x 15cm 70cm are tested for flexural strength.
The machine consists of a hand operated load frame. The lower platen has two rollers, the distance between which is adjustable. For 150mm x 150mm x 170mm beam, the centre to centre distance between the rollers is 600mm while it is 400mm for beams of size 100mm x 100mm x 500mm. The upper platen has also a pair of rollers whose distance is adjustable. It is 200mm centre to centre, for 150mm x 150mm x 700mm size beam and 133mm for 100mm x 100mm x 500 mm size beam. A pressure gauge to indicate load is fixed on the load frame. A small pumping unit is attached to the load frame. Total capacity of the machine is 100 KN and a 150mm dia pressure gauge 100 KN X 1 KN is fitted on the machine. Since this is a hand operated light weight machine, it is useful for field laboratory also.
