### Experimental evaluation of corrosion rate of rebars in M25 ...

01/06/2009 The M25 concrete mix was designed with the water cement ratio of 0.43 as per ACI 211-1-91 standard. The proportion of ingredients by weight of cement is arrived as 1: 2.31: 2.57. After 28 days of curing, the actual strength of this M25 grade concrete mix was obtained as 34.27 N/[mm.sup.2] which is greater than the required design strength specified by ACI 211-1-91 standard. Cubes of size 150 ...
