Instructions for use

Compatibility: Strumin Dura 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 of Strumin Dura 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 Dura is available in 25 kg pails.
Storage: Strumin Dura has a minimum shelf life of 6 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 Dura 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.

Fire

Strumin Dura is non-flammable.
