FLEXURE TESTING MACHINE (ELECTRICALLY OPERATED)

AS PER IS: 516 BS 1881, ASTM C78.

Introduction:

Flexural tests of concrete beam have their own importance in concrete Road Constructions as well as Buildings constructions. Normally concrete beams of sizes 10 cm x 10 cm x 50 cm or 15 cm x 15 cm x 70 cm are tested for flexural strength.

General Description and Specifications:

• The machine consists of a Electrically operated Motorised load frame.
• The lower platen has two rollers, the distance between which is adjustable.
• For 150mm x 150mm x 700mm beam, the center to center distance between the rollers is 600 mm, 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 200 mm center to center 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 150 mm dia pressure gauge - 100 KN x 1 KN is fitted on the machine.
• A separate electrically cum hand operated pumping unit housed in a cabinet is supplied.
• The pressure gauge 0-100 KN x 1 KN, On/off switch and a slow/fast level to control rate of loading are fitted on the front panel of the pumping unit.
• A facility for hand operation is provided.
• A micro switch and relay fitted inside the pressure gauge protects the unit from over loading.
