Concrete and Mortar Integral Waterproofing Admixture, Liquid

Struproof WL is water based Admixture and is supplied as a white liquid emulsion. Struproof WL is a multipurpose, concentrated liquid polymer for making modified concrete, mortars, screed and render with better performance, improved mechanical properties and lower penetration against water, chloride and some typical chemicals.

Advantages

• Allows a reduction in mix water content to be made without affecting workability, so reducing permeability.
• Provides integral protection, ensuring reduced permeability throughout the concrete and mortars.
• Integral protection is maintained even if surface damage occurs, unlike applied surface films or coatings.

Typical dosage

The optimum dosage of Struproof WL to meet specific requirements should always be determined by trials using the materials and conditions that will be experienced in use. This allows the optimization of admixture dosage and mix design and provides a complete assessment of the mix. As a guide, an addition rate of 1% to 3% by weight of cement.

Instructions for use

• Compatibility: Struproof WL 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 Struproof WL is suitable for use with all types of Portland cements and cement replacement materials such as PFA, GGBFS and microsilica.
• Dispensing: The correct quantity of Struproof WL 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 SW50 spray applied curing membrane should be used.

Packaging & Storage

• Struproof WL is available in 20 kg containers.
• Struproof WL 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

Struproof WL is mildly 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

Struproof WL is non-flammable.
