4in Steel Retainer Set for Unbonded Cylinder Capping

4in Steel Retainer Set for Unbonded Cylinder Capping

Unbonded capping pads and retainers are a reliable and efficient solution for compression testing of concrete cylinder concrete specimens. This system provides an alternative to traditional sulphur capping and grinding machine methods, offering a safer and more accurate way to conduct compression tests. The system consists of two steel capping retainers and two neoprene pads, which work together to distribute the test load uniformly and ensure reliable strength results. By using unbonded capping pads, you can achieve consistent and precise results, making it an essential tool for any laboratory or testing facility involved in concrete testing.

The 4in Steel Retainer Set are used with 4in Neoprene Pads (sold separately) for unbonded capping of 4in (102mm) diameter concrete cylinder concrete specimens. They hold and confine the neoprene pads and are placed at each end of the concrete cylinder before testing to ensure even load distribution on the flat surfaces of the two flat surfaces of the cylinders. Steel Retainers are made of alloy steel, machined to precise dimensions and plated inside and out to resist corrosion. Bearing surfaces are flat to 0.002in (0.05mm). Sold in sets of 2.

Sulphur capping and grinding is being replaced by unbonded capping pads and retainers which provide a reliable way to get even load distribution during testing.

Product Description

Unbonded capping pads and retainers is a safe, accurate and cost effective alternative to hot sulfur capping compounds for compressive strength testing of concrete specimens. This system includes 2 steel capping retainers and 2 neoprene pads, to distribute compressive load forces evenly during compression testing. The neoprene pads are 0.5in (12.7mm) thick and flow during compression to fill irregularities at the cylinder ends to get reliable strength results.

These unbonded capping pads and retainers are for use with 4in diameter concrete cylinders and suitable for testing concrete strengths from 1,500 to 6,000psi (10-40mPa). The steel retainer rings hold the neoprene pads in place at each end of the concrete test cylinder for a reliable and fast testing method.

Unbonded capping thick pads and retainers are easy to use, accurate and cost effective. Reusable up to 100 tests. A good investment for any laboratory or compression testing facility.

Features:

• 2 steel capping retainers and 2 neoprene thick pads for even load distribution
