In my opinion, the standard is very minimal and the demands of the specifiers and contractors over-ride the of the ASTM standard. Thanks for your valuable comments. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. I am talking about case in middle east. ASTM usually does not get involved in manufacturing processes, but only specifies the minimum standards of the units. Close this window and log in.

The Eng-Tips staff will check this out and take appropriate action. BS mention specifically about face mix concrete pavers.

Standard Specification for Solid Concrete Interlocking Paving Units

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 awtm installation.

The tensile splitting test is of no value since the pavers never see a similar loading because of the restraint and effects of the surrounding units.

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. This can effect the applicability of this factor based on the testing of the sample you referred to. If yes which standard is referred for this type of pavers?

Perhaps the supplier you mentioned can address the variation if they are active in writing the ASTM c9936. A typical concrete brick could be 12, psi. How important is the split tensile strength test for concrete pavers?

In c36 case, the ASTM contains a requirement that the the length to thickness of the unit be less than 4. This paver is a long one, size mm x 72mm x mm,which has great potential for tensile splitting. Is there any ASTM asm which has mention about face mix type 2 layer semi dry cast concrete pavers? I am working in Kuwait. Defense manufacturing is all about project manufacturing and project accounting. Kindly share your experience and knowledge.

Register now while it’s still free! Are you an Engineering professional? As you said,Tensile split strength has little effect if the pavers are of interlocking type. I agree with you that the ast, 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.
