CMD BY ACI METHOD

Features CMD BY ACI METHOD

This CMD app requires all inputs at a time and perform all required calculations.
All required inputs are:1.
Specific gravity of concrete ingredients2.
Water absorptions of all aggregates3.
Natural moisture contents of all aggregates4.
Loose unit weights of all aggregates5.
Ove Dry rodded unit weight of coarse aggregate6.
Fineness modulus of fine aggregate7.
Blending percentages of aggregates, if any8.
Specification requirements, if any9.
Chemical admixtures10.
Measuring box size adjustmentThe required inputs are:A.
Bulk specific gravitiesB.
Water absorption capacities C.
Natural moisture content (required during mixing the concrete)D.
Loose unit weight for the design of box sizesE.
Oven dry rodded unit weight for coarse aggregatesF.
Fineness modulus of fine aggregatesG.
Blending of aggregates (CA01 with CA02 and CS00 with NS) required to satisfy the gradationsH.
Specification requirementsI.
Chemical Admixture and water reducerJ.
Design of measuring box sizes (length, width and height)K.
Yield value, initially, is 1.
After adjustment and satisfaction of the required strength, calculated yield value might be less than one or greater than one.
If yield value is one, no adjustment is required.The necessary outputs are:1.
Calculations of all mix ingredients2.
Summary of mix proportions of ingredients for laboratory trials.3.
Final adjusted mix proportions for field use for plant mix.
4.
Final measuring box sizes for aggregates and water content for a bag of cement content for field in-situ mix.
