Neoprene Pads for Concrete Cylinders

Neoprene Pads are accurate, efficient, and economical for compressive strength tests of concrete cylinders and serve as a faster and safer alternative to sulfur capping. Gilson's Unbonded Neoprene Pads are sold as singles or in packs of 12 (only for 4 & 6in), and available sizes are 6in, 4in, 3in, and 2in diameter cylinders. Select a durometer rating based on the design strength of the concrete specimens.

Neoprene Pads

Neoprene Pads flow during compression to fill irregularities in the cylinder ends and assure load uniformity. Pads are economical and can be reused for up to 100 tests. 4in and 6in pads meet the latest ASTM C1231 and AASHTO T 22 specifications.

  • 50 Durometer Pads meet tensile strength and durometer requirements of AASHTO T 22 and are appropriate for compressive strengths from 1,500—6,000psi (10—40mPa)
  • 60 Durometer Pads are used for strengths from 2,500—7,000psi (17—50mPa)
  • 70 Durometer Pads are used for strengths from 4,000—7,000psi (28—50mPa)
  • Pads may be used for concrete strengths up to 12,000psi (80mPa) with additional qualification testing by the owner

Unbonded Capping pads are precisely sized to fit Gilson Steel Retainer Sets (which are purchased separately). Steel Retainer Rings hold tough 0.5in (12.7mm) thick Neoprene Pads. Rings and pads are positioned at each end of the concrete test cylinder to distribute compressive load forces evenly. Two Pads are required for compression testing of concrete cylinders.
