Lateral Extensometer

This is for the determination of lateral extension of 150 mm dia x 300 mm high cement concrete cylinders while testing them under compression. The extensometer consists of two movable frames pivoted at one end. A dial gauge measures the lateral extension, and a removable spacer strip is for the initial setting of the dial gauge. Mounting of extensometer on the specimen is with the help of screws. Supplied complete, with a dial gauge 0.002 mm x 5 mm. For determination of the change in size of a concrete or cement sample, brought about by a change in moisture content, following apparatus have been designed. Tests can be performed on freshly made specimens or specimens from existing structures.
