Instructions for use

Compatibility: Strumin MP980 is compatible with other STRUMIX admixtures used in the same concrete mix. All admixtures should be added to the mix separately and must not be mixed together prior to addition. The resultant properties of mixes containing more than one admixture should be assessed by the trial mix procedure recommended on this data sheet.
Dispensing: The correct quantity Strumin MP980 should be measured by means of a suitably accurate device; and then added to the concrete during the mixing process either by hand, or mechanically.
Curing: As with all structural concrete and sand : cement mixes, good curing practice should be maintained, particularly in situations where an overdose has occurred. Water spray, wet Hessian or a Strucure WS spray applied curing membrane should be used.

Packaging & Storage

Packaging: Strumin MP980 is available in Big Bag (400 kg - 600 kg)
Storage: Strumin MP980 has a minimum shelf life of 12 months at 35°C if kept in a dry store in the original, unopened packs. The shelf life will be reduced at higher ambient temperatures.

Health and safety

Strumin MP980 is alkaline and should not come into contact with skin and eyes. Avoid inhalation of dust during mixing. Gloves, goggles and dust mask should be worn. If contact with skin occurs, wash with water. Splashes to eyes should be washed immediately with plenty of clean water and medical advice sought.
