Metalcrete Industries Superslump
Metalcrete Industries Superslump is a liquid admixture for concrete and mortar that allows water reduction without sacrificing slump or workability. Through a chemical process, it internally lubricates the cement matrix to increase the efficiency of any cementitious system. This allows the production of concrete and mortars with higher strengths, better freeze/thaw resistance, and lower permeability. It can also be used to increase the workability of concrete and mortar while maintaining water content.

- Technical data
Typical Slump Increases:; Compressive Strength: Superslump vs. control at a 4 in. (102 mm) slump.; 2,300 psi (16 MPa); 2,800 psi (19 MPa); 3,900 psi (27 MPa); 5,000 psi (35 MPa)
- Benefits and Features
Easy to use by direct addition to concrete or mortar.; Reduces required water thereby enhancing hardened properties.; Normal set times virtually unaffected with normal dosage rates.; Contains no added calcium chloride or other corrosive agents.; Takes hard to work concrete to easily placed high slumps.; Can be used with air entrained systems.; Excellent for use as a pumping aid.
- Use Direction
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.
- Estimating and 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.
