Table 3. Minimum Design Resistance
| Clause No. | FOR | READ |
| 7.1.2. (page 8) | The compressive stress produced due to loading mentioned in Clause 5.2 (ii) shall not exceed 0.5 ¦cj. which shall not be more than 20 MPa, where ¦cj is the concrete strength at that time subject to a maximum value of ¦ck | The compressive stress produced due to loading mentioned in Clause 5.2 (ii) shall not exceed 0.5 ¦cjwhere ¦cj. is the concrete strength at that time subject to a maximum of 30 MPa. For concrete of compressive strength greater than M 60, this Clause may not be applicable and the values of permissible temporary stresses in concrete may be obtained from specialized literatures and experimental results. |
