This apparatus is used for determination of the strain and deformation characteristics of cement concrete cylindrical specimens of 150 mm dia x 300 mm long.
The Compressometer consists of two frames for clamping to the specimens by means of five tightening screws with a hardened and tapered end. Two spacers hold the two frames in position. An adjustable pivot rod rests on pivot screws. A spring enables the pivot rod to remain in contact with pivot screws. The Ball chain is for adjusting the tension of the spring. A dial gauge, fixed to a bracket, fitted to the top frame, is used for taking deformation measurement. Supplied complete, with a dial gauge 0.002 mm x 10 mm, in a wooden carrying case.
