The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. This can effect the applicability c36 this factor based on the testing of the sample you referred to. Kindly share your experience and knowledge. To my knowledge, the the units you have visualized are not the typical “interlocking concrete pavers” that the specification written for, which is for heavy loads wheel loads than can be carried if installed properly.
I agree with you that the standard is very minimal, but when we deal the subject in construction contracts,though we specify the product with manufacturer name,the reference to International standards becomes mandatory. The face layer does present some problems regarding determining durability testing, but does not preclude the use of a face layer, since it is a standard for type of construction material.

How important is the split tensile strength test for concrete pavers? Combining values from the two systems may result in non-conformance with the standard. Register now while it’s still free! The psi compressive strength requirement is very low and a manufacturer could not afford to make the minimal units because this would require compromising other factors including handling and installation.
