If yes which standard is referred for this type of pavers?
A typical concrete brick could be 12, psi. This paver is a long one, aztm mm x 72mm x mm,which has great potential for tensile splitting. Engineer and international traveler interested in construction techniques, problems and proper design. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. Click Here to join Eng-Tips and talk with other members! 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 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.
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.

Red Flag This Post Please let us know here why this post is inappropriate. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Work Item s – proposed revisions of this standard.
The Eng-Tips staff will check this out and take appropriate action. The use of pavers made using a wet cast method is not common because the wet cast units are probably not cost effective.
It is informational only and not an official part of the standard; the full text of the standard itself must be referred asmt for its use and application.
Close this window and log in. In my opinion, the standard is very minimal and the demands of the specifiers and contractors over-ride the of the ASTM standard. 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 9c36 construction material.
This can effect the applicability of this factor atsm on the testing of the sample you referred to.

ASTM Standard for Concrete Unit pavers sudhirvasan – If you refer to a standard ASTM or others in your specifications, make sure you understand the specification and f936 the requirements that sstm excluded or waived for your specific use.
BS mention specifically about face mix concrete pavers. Resources Digital Transformation may be defined in a number of different ways by f936 or enterprise software vendors.
This specification is intended for interlocking concrete pavers used in the construction of paved surfaces and manufactured from cementitious materials, aggregates, chemical admixtures, and other constituents such as integral water repellents.

Download Now Defense manufacturing is all about project manufacturing and project accounting. Which abrasion resistance test is more recommended for concrete unit pavers? ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. Dear All, Kindly help me with your expertise knowledge in the below questions.
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.
There are also very few if any manufacturers that meet the standards for the installation requirements.
Thanks for your valuable comments. Combining values from the two systems may result in non-conformance with the standard.
Thank you Mr Dick. It’s easy to join and it’s free. ASTM usually does not get involved in manufacturing processes, but only specifies the minimum standards of the units. The compressive strength is far below the level of the usual manufacturing equipment.
