Modulus of elasticity, modulus of rupture and compressive strength relationships of concrete containing GGBFS

摘要

Dear Sir, This has reference to the paper titled 'Modulus of elasticity, modulus of rupture and compressive strength relationships of concrete containing GGBFS' authored by M. Shariq, J. Prasad, A. Masood and A.K. Ahuja, published in the November 2013 issue of The Indian Concrete Journal (Vol. 87, No. 11 pp. 53-60). I appreciate the author's work for finding out the values experimentally and indeed it is a good work done by them. I have a small doubt in the concrete mix proportions as printed in Table 2 [vide page number 55]. The quantities of cement, FA, CA, w/c ratio given for the Mix ID (mentioned in the above Table 2) are presented in the table shown below.
