This Concept Map, created with IHMC CmapTools, has information related to: ACI 211 Concrete Mix Design, Recheck slump lb/ft^3 Determine unit weight, Remix for 3 mins ???? Recheck slump, Non Air-Entrained Concrete Step 7 Estimate Fine Aggregate Content, Add 2/3 of water to the mixer ???? Mix for a few revolutions, Add the fine agg, cement, and rest of the water to the mixer ???? Mix the batch, If slump is too low ???? Add water and cement to batch, Air-Entrained Concrete Step 4 Select w/c Ratio, Choose Max Aggregate Size inches Non Air-Entrained Concrete, Perform the slump test ???? If slump is too low, Calculate Cement Content Step 6 Estimate Coarse Aggregate Content, Estimate Coarse Aggregate Content lb/yd^3 Air-Entrained Concrete, Determine unit weight ????
