Normal Concrete Mix Design based on DOE Method - Unrestricted Design

[@odysseusrobert6615]

Hi miss, may I know if there is any possible way for me to get this complete standards of the book Design of normal concrete 2nd edition?

What if we have both uncrushed and crushed aggregate in 1.6? Do we assume 2.65 or just take 2.6/2.7?

Thank you. Very important sharing.

Thank you.

macam kenal suara ni hehehe Dr. ajar subject structure design

[@khalidali3141]

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 😕

what if the cement content is larger than both maximum and minimum? 17:57

[@structureandmaterialincivi5611]

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.

bien hecho

what does mean of unrestricted design?

[@structureandmaterialincivi5611]

There is no maximum and minimum cement content.

Thank you

You are most welcome

what if data didn't give the min cement data and the 3.1 is larger

[@structureandmaterialincivi5611]

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
