(2) This selection of the manual explains how to make the necessary conversions using four sample

worksheets. Along with the conversions these worksheets are also used to find the mix settings required for an individual

mixer unit. To make a permanent record of mix settings, a sample mix settings chart is shown.

f. Control Data Worksheet. (See fig. 2-2.)

(1) Basic Information (1). This information pertains to ingredients, mix design and mixer data and is the basis

of all calculations. All data is lettered and these letters will be used as a reference to perform the calculations on the

worksheet. In some cases you may not get the information to complete both pounds of cement cu-yd (F) and bags of

cement cu-yd (G); therefore, you may have to calculate one or the other. Calculate as follows:

(a) If you do not know bags of cement (G), divide pounds of cement by weight per bag.

(2) Cement Meter Count (2). In this calculation (T) refers to time or "count" on the meter-register.

(3) Sand Dial Setting (3). In this calculation (X) refers to the answer of your first calculation. The (S) refers to

the answer of your second calculation and is the number used to determine the setting using mix setting graph (fig. 2-3) for

standard sand.
