WHERE TO USE
Duramix is used in plasters, screeds and mortars, to reduce absorption of water and moisture proceeding from the soil, rain water splashing the surface or moisture in the air.
HOW IT WORKS
The addition of Duramix to the mix will provide hydrophobic Properties. Duramix acts as a non-wet able lining on the walls of all pores and voids in the mix, making them water resistant. Duramix “built-in” water barriers guards against damage caused by water infiltration.
ADVANTAGES
The addition of Duramix will reduce the amount of water that permeates through the concrete. Reducing the passage of water will provide beneficial advantages by:
Increasing resistance to weathering
Wetting and drying
Freezing and thawing
Increase resistance to chemical attack
Reduce the potential for efflorescence
Reduce the probability of corrosion of embedded metal
ADDITION RATES
The amount of Duramix necessary for a specific mix depends upon the degree of water resistance desired. Suggested addition rates For Duramix in ready mixed or pre-cast concrete are 1-3 liters per bag of cement.
COMPATIBILITY
Duramix can be added to mixes containing other admixtures. Testing with actual materials should be done to determine Performance; each admixture must be added separately to the Mix, do not allow any of
the admixtures to contact each other before they enter the mix.
AIR CONTENT
Added by itself, Duramix may have a slight effect on the entrained air volume. Trial mixes or field tests are recommended to evaluate its effect with your material at your plant. Overdosing can cause variations in air content.
CURING
Proper curing of the in-place mix is vital. Allowing the mix to pre-maturely dry out should be prevented because re-wetting may not be effective.
DESPENSING
It is recommended that Duramix should be dispensed into the concrete and thoroughly mixed to provide complete dispersion.
Duramix can be added at any point during the charging of the mixer.
PACKING
FREEZING POINT
Duramix will freeze at approximately 5°C and cannot be remixed after freezing.
FLAMABILITY
None
