The specification also offers guidelines for physical requirements, sampling and testing, visual inspection, and rejection of specimens. What is common practice in US? Engineer and ast traveler interested in construction techniques, problems and proper design.
Is there any ASTM standard which has mention about face mix type 2 layer semi dry cast concrete pavers? Work Item s – proposed revisions of this standard. There are some features incorporated sstm the design asym the paving units are not even addressed in C Which abrasion resistance test is more recommended for concrete unit pavers?

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.
Dick Engineer and international traveler interested in construction techniques, problems and proper design. 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 c9336 of construction material.

Historical Version s – view previous versions of standard. This can effect the applicability of this factor based on the testing of the sample you referred to. Perhaps the supplier you mentioned can address the variation if they are active in writing the ASTM standard.
This abstract is a brief summary of the referenced standard. ASTM Standard for Concrete Unit pavers sudhirvasan – If you refer to a standard ASTM or others in your specifications, make asfm you understand the specification and note the requirements that are excluded or waived for your specific use.
Dear All, Kindly help me with your expertise knowledge in the below questions. The use of pavers made using a wet cast method is not common because the wet cast units are probably not cost effective. Red Flag This Post Please let us know here why this post is inappropriate.
A typical concrete brick could be 12, psi. The Eng-Tips staff will check this out and take appropriate action. In your case, the ASTM contains a requirement that the the length to thickness of the unit be less than 4. ASTM usually does not wstm involved in manufacturing processes, but only specifies the minimum standards of the units.
ASTM C / CM – 18 Standard Specification for Solid Concrete Interlocking Paving Units
I am working in Kuwait. The compressive strength is far below the level of the usual manufacturing equipment.
Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Atm values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. In my opinion, the standard is very minimal and the demands of the specifiers and contractors over-ride the of the ASTM standard.
Link to Active This link will always route to the current Active version of the standard. Thanks for your valuable comments. How important is the split tensile strength test for concrete pavers?
Standard Specification for Solid Concrete Interlocking Paving Units
The tensile splitting test is of no value since the pavers never see a similar loading because of the qstm and effects of the surrounding units. Kindly share your experience and knowledge. Thank you Mr Dick.
It is informational only and not an official part of the 9c36 the full text of the standard itself must be referred to for its use and application. 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 am sure they have had units tested in a lab somewhere that may have an acceptable machine to test such a long unit if the ASTM standards were used. It’s easy to join and it’s free.
