IT IS HIGHLY RECOMMENDED THAT THE TECHNICAL DEPARTMENT BE CONTACTED PRIOR TO THE USE OF MOXIE 1800 SUPER-ADMIX.

Field and laboratory tests show maximum benefits have been achieved at a recommended slump range of:

3" to 3½" for standard concrete, 

2" to 2½" for fly ash,

do not exceed a .52-.54 water to cement ratio regardless of slump.

Higher slumps will result in lower performance and increased concrete hydration time resulting in an increase in the curing time required for the chemical reaction of MOXIE 1800 SUPER-ADMIX.

Refer to the MOXIE International publications, "Moisture Migration Table" and "Water Vapor Flow Rates".

Refer to the slump and water cement/ratio as specified by the Architect and ASTM C94 - Standard Specifications for Ready-Mixed Concrete.

1) Start with a clean mixer drum on the truck, clean as usual thereafter.

2) Add the proper dosage of MOXIE 1800 SUPER-ADMIX a minimum of 20% of the amount of water to the mixer drum. In central mixing plants. Standard dosage rate is 10 oz per sack of cement, per cubic yard of concrete. Add after water/cement ratio adjustment to the mix design, then add the proper amount of MOXIE 1800 SUPER-ADMIX. Example: 5½ sk mix X 10 oz. sk/cy = 55 oz. per cubic yard.

 NOTE: If polyfibers or coloring agents are specified they should be added at this time and mixed thoroughly.

3) Rotate the drum for approximately 30 revolutions (2-3 min.) only to insure thorough mixing (ASTM. C94).

4) Add the remaining amount of water, (minus the amount of MOXIE 1800 SUPER-ADMIX used), and the dry cement, aggregate, and sand. In central mixing plants MOXIE 1800 SUPER-ADMIX may be added to the entire weighed amount of water, minus the amount of MOXIE 1800 SUPER-ADMIX used, batch as usual.

5) Rotate the drum for approximately 15 minutes, 70-100 revolutions, at no less than 4 rpm before discharging, as called for in standard ready mixed practices.

THIS TIME IS NOT IN ADDITION TO THE STANDARD MIXING TIME. REFER TO ASTM C94

6) Returning trucks should be washed out as usual.

1) Do not use any curing compounds. Fog only with water if necessary. Do not flood surface. Flooding will cause shrinkage cracking.

2) If ambient temperature drops below 50oF rotate mix drum an additional 4 -5 min. at mix speed, on-site, prior to discharging. MOXIE Fastset50 Accelerator, a non-chloride, set accelerator may be used to reduce set time up to 50 percent at maximum dosage. Consult the Fastset50 Accelerator cut sheet or MOXIE International for dosage.

3) Maximum benefits have been achieved maintaining a 3" to 3½" slump, 2" to 2½" for fly ash mix designs.

4) Concrete will appear to be dry, however it will have the workability and finishing characteristics of a slump that is 1½" to 2" higher. At the above water to cement ratio there will be virtually no bleed water, do not allow finishers to wait for it. If there is any bleed water the water to cement ratio is too high, reduce the amount of water.

5) Less line pressure is required for pumped concrete. Typical line pressure reduction would be approximately one-third. Example: 1500 psi would reduce to about 900-1000 psi.

6) If there are any additional requirements please contact Technical Services.

TAKE NECESSARY SAFEGUARDS AND PRECAUTIONS, PROVIDE ADEQUATE PROTECTION FOR THE SLAB DURING

THE FIRST 72 HOURS AGAINST FREEZING

OR 7 DAYS IN HIGH TEMPERATURES.
