Dear Er Mallick,

I corrected your document and it is enclosed.

Hope it is clear now. You have to follow Table 11 only. There is no confusion.

Regards,
NS

Dear Er Arvind,

Thanks. I could download see all  the 8 pages. Interesting to note this criteria was originally from Australian code and then from British code!  Please note that page 34, which may contain imp. conclusion is missing, instead you have copied page 33 twice. Hence please send page 33. Till page 33, Dr Iqbal Ali says that  there were some problems in the 1978 version and that they have been rectified in 2000 version. Of course as indicated already by Er Mithilesh  there was an Amendment to this clause and it has been described in the earlier postings.  

Regards,
Subramanian

Dear Er Mallick,

It may be interesting for you to compare IS provisions with ACI provisions. In ACI, If concrete strength is less than M35, the strength should be larger of (1) fc + 1.34 s and (2) fc+ 2.33 s -3.45. If concrete steength is greater than M35, the strength should be larger of (1) fc + 1.34 s and (2) 0.9fc+ 2.33 s, where s is the std. deviation.

Regards,
NS

Dear Dr Subramanian,

Sorry I didnot realise that this page was missing. Please find the page 34. Please note that page 34 earlier sent is actually page 33.

Dear all
Let us remember that the Indian Codes are based on charactersitic concrete strength of 95% probability with 28 day strength tests on 150 mm cubes. This is not the case with ACI provosions.

Dear All,

Further to add here that very recently, Central Vigilance Commission of India has issued a circular dated 07.10.2010 regarding non-compliance of codal provisions of IS 456 : 2000 for Design Mix Concrete and Acceptance criteria of concrete read with amendment no. 3 of 2007. I think all designers/engineers at field formations/contractors/developers should be aware of that.
