Most crystalline companies are dosing their waterprooﬁng admixtures as a percentage of cement content. As the cement content increases, the dosage of waterprooﬁng admixture also needs to be increased.
But if, as happens regularly, variations are made to the mix design it is necessary to vary the quantity of waterprooﬁng admixture. Unfortunately this is often forgotten, resulting in incorrect dosages and possible leakage.
CWS Admix has a ﬁxed dosage per cubic meter of concrete (0.8 kg/m3 or 22oz/yd3), regardless of concrete mix design. This:
• Provides simplicity in calculating the right quantity
• Provides security against human error
• Provides peace of mind that if the mix design is altered, the waterprooﬁng will still be correct
• Provides peace of mind that the job is done correctly
Fixed dosage is a very strong reason for Consultants and Contractors to adopt CWS Admix!
CWS Admix versus other Crystalline products
CWS Admix : Dosed at 0.8 kg/m³ per cubic metre of concrete (22oz/yd3). Regardless of cement content.
Other crystalline : Dosage varies according to cement content. Calculation has to be made for every pour.
Usually these variable dosage calculations are based on dosage charts which can be confusing, are diﬃcult to use and result in incorrect dosages and accordingly: leakage. This can result in some very expensive mistakes.
