If for reasons stated in 4.10.5.1 it is determined that add water will be dispensed into truck mixer, then a sample from the mix, af ter add water and af ter truck mixer has revolved 30 times at mixing speed, must be slump tested before dis-charge.
b.
Preceding procedure may be repeated as necessary before mix discharge until desired slump or workability is attained.
4.10.5.3 Maximum slump shall not be exceeded as a result of the addition of add water to the mix.
4.10.5.4 Quantity of add water shall not exceed quantity recorded for " add water" on the batch ticket.
4.10.5.5 Add water will be measured by an accurate water meter or calibrated container to the nearest whole gallon and quantity shall be so noted on batch ticket in "A00 WATER" block.
4.10.5.6 Responsible contractor representative and testing lab reoresentative will each sign within the block, before water is added, to verify that the add water about to be added does not result in the total add water quantity exceeding the quantity recorded for " add water" on the batch ticket.

REVISION 2, March 9, 1976 PAGE 13 of 21 4.10.5.7 CALCULATION OF ALLOWABLE " ADD WATER" The cards will be punched to show the total " design water" or less, such as 230 lb/cy for Mix I.D. No. 202. The Batch Plant operator will deduct water as outlined below using the slump control meter.
This deduction will be sufficient to orovide required slump for the mix classification i.e. 3" for mass concrete and 4" for regular concrete.
For Aggregate Moisture compensation the batch plant control system automatically subtracts the free moisture contained by the fine aggregate from the total " design water" (230 lbs, for Mix !.D. No. 202). The free moisture in the coarse aggregate is calculated by the B&R batch plant personnel using the latest Hunt report on the C.A. moisture. The cuantity obtained by sub-tracting the F.A. free moisture + C.A. free noisture from the total " design water" is the " maximum amount" of water which is allowed to be dispensed into the mix.
If the " maximum amount" of water is not dispensed at the batch plant, then " add wate'r" may be added into the truck mixer later at the point of discharge.
The allowable " add water" is calculated by subtracting the " water
/
')
dispensed at batch plant" from the " maximum amount" and is written IJV by B&R batch plant personnel in the Add Water block on the batch ticket.
Add Water = Design Water - (F.A. free moisture)
- (C.A. free moisture) - (water dispensed at batch plant) 4.10.6 Same as Section 4.8.4.
4.10.7 Same as Section 4.8.5.
