RE: Concrete mix designs

There is a "concrete" forum not far below "structural".

Buy a dictionary, keep it nearby and USE it. Webster's New World Dictionary of American English is recommended, and Webster's Collegiate Dictionary.

RE: Concrete mix designs

Always put in 3-7% air entrainment for outside, freeze thaw and expansion for hot climates.

RE: Concrete mix designs


What is your question or concern regarding the mix design? It sounds like you're asking us to do your job. Are you familiar with concrete mix design?

RE: Concrete mix designs

If non-curl is of primary importance in your mix 1, you may want to consider Type K, shrinkage-compensating cement. It eliminates sawcut joints as well.
