Alternatively, the superplasticizer may be added manually to the back of the truck by a trained technician, if this procedure is confirmed by historical data to yield a uniform and acceptable product. Mix the concrete a minimum of six minutes after addition of the superplasticizer and before discharge.

D. Re-tempering with superplasticizer is prohibited.

2. The amount of water added at the site is accurately measured to ± 1 gallons of the desired added amount.

3. That water addition is followed by 3 minutes of mixing at mixing speed prior to discharge.

4. Standard cylinder samples as required by these Specifications are taken after addition of water.

5. The person authorized to add water shall be mutually approved by Engineer, Contractor, and Ready-Mix Producer.
