the use of entrained air. In 1970 among other modifications the IS mix design showed better results both at the age of 7 days and 28 days which gives IS mix design a clear edge over the ACI mix design for both economy and test ...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.ACI 301 provides very broad guidelines for Quality Control • Maintain records documenting each material used • Ensure that production and delivery conforms to measuring

ACI should be preferred for mix design without plasticizer.
