Introduction Compressometer The Compressometer is used for evaluating deformation and strain characteristics of concrete cylinders while undergoing compression testing. The Compressometer includes two cast aluminum-alloy yokes, mounting and central points, stainless steel control rods. Models are available with a dial gauge— with a range of 0.2" (5.08mm) and minimum graduations of .0001 (.0025mm), as well as with a digital indicator or a LSCT transducer.
The Concrete Cylinder Compressometer-Extensometer is used to determine the static modulus of elasticity (Young's Modulus) and Poisson‘s ratio of concrete in compression. The instrument complies with the specifications of ASTM C469. Using the H-2912, measurement of axial deformation and diametrical extension can be made on 6" dia x 12" to 16" length, high-molded concrete cylinders and diamond-drilled concrete cores, when longitudinal compressive stress is applied on the specimens.
8 Remove the two spacer rods 9 Remove the three metal blocks from under the lower ring. 10 Zero the axial strain dial indicator with the stem close to the fully extended position. Zeroing can be done (I) by rotating the dial face after loosening the lock screw on the upper right hand side of the dial indicator or (2) by adjustment of the contact post that fits into the lower lock ring. 11 Zero the diametrical strain dial indicator with its stem close to the fully pushed-in position.
Maintenance 1 Occasionally oil the steel portions of the instrument, screws, spacer rods, nuts, etc. 2 Care should be taken in handling the device in order to avoid any misalignment of parts. HM-2325A.3F HM-2330D.3F Data Acquisition Setups— You can fully automate your test data collection by using one of these MiniLoggers. The MiniLogger is a simple-to-use, four channel, stand-alone data-logging system, which can collect data generated from digital indicators or LSCT transducers. Use model HM-2325A.
