- Estimating/Coverage
To properly dose with Superslump, the cement factor or content of the concrete or mortar must be known. Most applications will use 10 oz. (0.30 liter) to 14 oz. (0.40 liter) of Superslump per 100-lbs. (45 kg) of cement. The normal maximum range is 6 oz. (0.18 liter) to 18 oz. (0.52 liter) per 100-lbs. (45 kg) of cement.
- Directions for Use
- Preparation: Normally, standard concrete or mortar mixes should be mixed with an approximately 30% water reduction as a starting point. Add Superslump and mix for 3 minutes and check for desired slump or flow. Add additional water to make final adjustments and mix for 2 additional minutes. Keep track of water and Superslump dosage for additional batches. On applications where additional slump or flow is needed, add Superslump to the standard mix and blend for 3 to 5 minutes. Adjust Superslump to achieve desired workability. Concrete utilizing Superslump will flow farther and expect greater form pressures than with standard concrete. Forms should be built accordingly.
