ACI METHOD OF PROPORTIONING CONCRETE MIXES

ACI METHOD OF PROPORTIONING CONCRETE MIXES The ACI Standard 211.1 is a “Recommended Practice for Selecting Proportions for Concrete”. The procedure is as follows: Step 1. Choice of slump Step 2. Choice of maximum size of aggregate Step 3. Estimation of mixing water and air content Step 4. Selection of water/cement ratio Step 5.

Nominal Mix and Design Mix of Concrete: Know the Difference

In the nominal mix concrete, all the ingredients and their proportions are prescribed in the standard specifications.These proportions are specified in the ratio of cement to aggregates for certain strength achievement.. The mix proportions like 1:1.5:3, 1:2:4, 1:3:6 etc. are adopted in nominal mix of concrete without any scientific base, only on the basis on past empirical studies.

Concrete mix ratio for various grades of concrete

“M” stands for “mix”. Mix represents concrete with designated proportions of cement, sand and aggregate. And the number following “M” represents compressive strength of that concrete mix in N/mm 2 after 28 days. For example, for M20 grade of concrete mix, its compressive strength after 28 days should be 20 N/mm 2.
