Which abrasion resistance test is more recommended for concrete unit pavers? Students Click Here Join Us!
The tensile splitting test is of no value since the pavers never see a similar loading because of the restraint and effects awtm the surrounding units. 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 atm to International standards becomes mandatory. ASTM Standard for Concrete Unit pavers sudhirvasan – If you refer to a standard ASTM or others in your c96, make sure you understand the specification and note the requirements that are excluded or waived for your specific use.
In my opinion, the standard is very minimal and the demands of the specifiers and contractors over-ride the of the ASTM standard. BS mention specifically about face mix concrete pavers.
This abstract is a brief summary of the referenced standard. The specification also offers guidelines for physical requirements, sampling and testing, visual inspection, and rejection of specimens.
There are also very few if any manufacturers that meet the standards for the installation requirements. By joining you are opting in to receive e-mail. Download Now White Paper: If yes which standard is referred for this type of pavers? Referenced Documents purchase separately The documents listed below axtm referenced within the subject standard but are not provided as part of the standard.
Is there any ASTM standard which has mention about face mix type 2 layer semi dry cast concrete pavers? The asgm 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. Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.
Perhaps the supplier you mentioned can address the variation if they are active in writing the ASTM standard. How important is the split tensile strength test for concrete pavers? Thank you Mr Dick. 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.
ASTM usually does not get involved in manufacturing awtm, but only specifies the minimum standards of the units. What is common practice in US? The Eng-Tips staff will check this out and take appropriate action. There are some features incorporated in the design of c396 paving units are not even addressed in C It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use astmm 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. Thanks for your valuable comments. I am talking about case in middle east.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. The face layer does atsm some c93 regarding determining durability testing, but does not preclude the use of a face layer, since it is a standard for type of construction material. Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.
Kindly share your experience and knowledge. 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. I am working in Kuwait. In your case, the ASTM contains a requirement that the the length to thickness of the unit be less than 4. The use of pavers made using a wet cast method is not common because 9c36 wet cast units are probably not cost effective.

Combining values from the two systems may result in non-conformance with the standard. This paver is a long one, size mm x 72mm x mm,which has great potential for tensile splitting. Link to Active This link will always route to the current Active version of the standard.
