Concrete Mix Evaluator (CME)
CME Laboratory Calculator
Labortory Batch Calculator
Always check your yield on labortary batches
1. Enter your laboratory batch size, example: 1.5 cubic feet
2. Enter your TOTAL moisture of aggregates
3. Labortory batch weights are calculated and adjusted for moisture
Rule of thumb for adjusting the laboratory batch for slump and water addition - one gallon of water per Yard is equal to 0.463 lbs. of water in this laboratory batch example -see upper left
Entering the plastic density will trigger the calculation of the laboratory yield and relative yield.
Water withheld or added can be entered in "lbs." or "ml"
CME will calculate the new aggregate proportions to accommodate addition or subtraction of water
