The Perpendicularity Verification Device (PVD) is a new tool to verify proper alignment of concrete cylinders during compressive strength testing. Latest revisions to ASTM C39 require verification that alignment is within ±0.5° of vertical for each specimen tested when Unbonded Caps are used. After specimen loading has commenced, but before reaching 10% of total load, the PVD is held on the bottom machine platen and manually positioned against the cylinder. The included Gap Measurement Tool is used to check the gap between the device and cylinder. If the Tool will not pass through the gap, the test can continue. The PVD's feature unique designs for use with 4x8in (102x203mm) or 6x12in (152x305mm) cylinders and are simple, lightweight and easy to use. A recess cut at the bottom eliminates interference from Retaining Rings and spacers during use. Sturdy Machined aluminum construction.

MCA-44 PVD is used for 4x8in (102x203mm) specimens in compression machines where 4in (102mm) high spacer blocks are used for proper positioning of the cylinder.

MCA-44N PVD is designed for use with 4x8in cylinders in compression machines where no spacer block is in use.

MCA-46 PVD fits 6x12 concrete cylinders in all machines.

Features:

  • Sturdy, precision machined aluminum
  • Notched bases prevent contact with Retaining Rings and Spacers
  • Meets new ASTM C39 requirements

Included Items:

  • Perpendicularity Verification Device (PVD) for 4in or 6in concrete cylinders
