Product Description

Longitudinal Compressometer

Used for determination of modulus of elasticity of concrete using 15 cm dia x 30 cm high cement concrete cylinders subjected to compressive loads. The apparatus consists of two annular frames of cast aluminum alloy with two gauge bars. The bottom frame is provided with three clamping screws with hardened conical ends to hold the specimen at two diametrically opposite points. Both the frames are joined together with a pivot rod and tensioning spring. On the diametrically opposite end of the pivot, a dial gauge of 0.002 mm x 5 mm range is fitted to the top frame with a bracket. The plunger of the dial gauge rests on an anvil fixed to the lower frame. The dial gauge records the deformation of the specimen under compression. Supplied complete in a wooden box.

Lateral Extensometer (150 mm dia)

For measuring the lateral extension of 15 cm dia concrete cylinders during the compression test. The apparatus consists of two semi-circular frames pivoted at one end and carrying a dial gauge of 0.002 mm x 5 mm range at the other. Four clamping screws are provided for initial setting of the instrument. The dial gauge records the deformation readings magnified 2.5 times.
