Mam what if, maximum size of coarse aggregate is 13mm rather than 20 mm, then how can we determine the free content ,as in the maximum size of caorse aggregates are 10mm,20mm,40mm, plz guide me i'm so confused 😕
If the cement content calculated using equation C3 is larger than maximum cement content and minimum cement content, it is thus impossible to continue the mix design. Amendment need to be done by change the type of cement or cement strength class or both.
1. If cement content in 3.1 larger than maximum cement content (item 3.2), you can't proceed the design. 2. If cement content in 3.1 less than minimum cement content (item 3.3)., use 3.3 3. If there is no data for item 3.3, you may proceed with calculated cement content as in 3.1
