ASTM 1231 4in Neoprene Concrete Cylinder Pad Caps, 70 Durometer Defined Hardness (24/Pack)
The Neoprene Compression Pad flows into irregularities and distributes the test load uniformly without creating air pockets so the force from the machine is applied evenly. Unlike bonded caps, unbonded caps have specific safety considerations and limitations that must be taken into account.
Refer to ASTM C1231 for max uses, qualification test, etc. Price is per full carton. Make sure to determine the correct conditions and methods for testing to ensure safety.
Compression pads are available in several durometers.
-
50 duro for design strength 1500 to 6000 psi
-
60 duro for design strength 2500 to 7000 psi
-
70 duro for design strength 4000 to 12000 psi
Establish safety and health practices when using unbonded caps. Users must follow health practices to ensure safety protocols are in place.
Two are required for compression testing of concrete cylinders and must be used separately in SI units and inch-pound units to avoid non-conformance with standards.
Compression pads are available in several durometers, including level neoprene caps which can be used under specific conditions. Unbonded caps can be used in lieu of conventional capping methods described in other standards. For a comprehensive understanding of the tools involved in concrete testing, such as essential concrete testing equipment, refer to the 'Manual of Aggregate and Concrete Testing' for detailed safety practices.
Per ASTM C1231, each pad can be reused up to 100 times. Make sure to count the number of uses to ensure compliance. Reuse is allowed under specific conditions and the requirements for the caps' properties must be met. Users have the responsibility to ensure safety with regulatory standards. Follow guidelines for reuse limits to stay safe. Note that unbonded caps may break more violently than bonded caps so safety considerations are critical. User must follow safety standards to prevent hazards. For more information on managing privacy settings and data practices.

Product Details ASTM C1231 is a standard practice for using unbonded caps in the determination of hardened concrete cylinders. This standard provides a practical alternative to traditional capping methods, time and cost savings. Using unbonded caps as per ASTM C1231 C1231M ensures accurate and reliable results in compressive strength testing of concrete cylinders like those achieved with the Capping Concrete Cylinders, Humboldt Kit. By following this standard you can get consistent and reliable measurements which is important for evaluating the quality and performance of concrete in construction projects.
ASTM C1231 C1231M is used for the use of unbonded caps in the determination of compressive strength of hardened cylindrical concrete specimens, including molded cylinders and cores from concrete structures. This standard is used in aggregate and concrete testing to test compressive strength of concrete. The standard is used in acceptance testing of concrete with compressive strength below 10 MPa [1500 psi] or above 80 MPa [12 000 psi]. This wide range of uses makes ASTM C1231 a useful tool for concrete quality and durability in various construction projects.
Features
-
Unbonded capping system for hardened concrete
-
Elastomeric materials like neoprene caps as an alternative to traditional capping systems
-
Defined hardness of elastomeric materials for consistent results
-
Specified maximum number of reuses without qualification testing up to a certain concrete compressive strength level
-
Qualification testing is required for all elastomeric materials other than neoprene regardless of the concrete strength
-
Safety precautions to prevent lateral spreading and ensure safe testing
The unbonded capping system for testing hardened concrete cylinders has several features that make it reliable and efficient. Elastomeric materials like neoprene caps are a practical alternative to traditional capping systems. These materials have defined hardness for consistent results. Each pad can be reused up to a specified maximum number without qualification testing if the concrete compressive strength is within the defined range. For elastomeric materials other than neoprene, qualification testing is required regardless of the concrete strength. Safety precautions are necessary to prevent lateral spreading and ensure safe testing of hardened concrete.
Standards and Certification
ASTM C1231 C1231M is a standard by American Society for Testing and Materials (ASTM). This standard can be used with other ASTM standards such as Practices C31/C31M or C192/C192M or Test Method C42/C42M. Using ASTM C1231 C1231M ensures compliance to internationally recognized principles on standardization as per the Decision on Principles for the Development of International Standards, Guides and Recommendations by the World Trade Organization Technical Barriers to Trade (TBT) Committee. A license is required to the full standard. By following these standards you can ensure your testing methods are in line with global best practices and get more credibility and accuracy in your results.

Testing and Standards
Testing of hardened concrete cylinders is an important process in the construction industry and requires adherence to specific standard practices. The standard practice for using unbonded caps in the determination of compressive strength of hardened cylindrical concrete specimens is outlined in ASTM C1231. This standard provides a practical alternative to traditional bonded capping methods, time and cost savings. The unbonded capping system is designed to distribute the load from the bearing blocks of the testing machine to the ends of the concrete or mortar specimens uniformly. The elastomeric pads deform in initial loading to conform to the contour of the ends of the test hardened cylindrical concrete specimens and are restrained from excessive lateral spreading by plates and metal rings. The standard requires that the values stated in either SI units or inch-pound units be regarded separately as standard and combining values stated from the two systems may not conform to the standard.
Applications and Use Cases
ASTM C1231 has many applications including aggregate and concrete testing, testing of concrete cylinders molded according to Practices C31/C31M or C192/C192M and testing of cores according to Test Method C42/C42M. The standard is used in acceptance testing of concrete with compressive strength below 10 MPa or above 80 MPa. The unbonded capping system is useful for concrete quality and durability in all construction projects and gives accurate and reliable results in compressive strength testing of concrete cylinders. The Neoprene Compression Pad flows into irregularities and distributes the test load uniformly without creating air pockets to give consistent breaks. For handling concrete test cylinders safely, consider using a Concrete Cylinder Lifting Device which can aid in transporting specimens conveniently. The force from the testing machine is applied evenly and compression pads are available in several durometers to suit different design strengths.
