KKS® POLYMAD 720 is a new generation admixture, contains poly-carboxylate ethers (PCE) polymers. It is specially designed to achieve high water reduction and prolonged setting time for concrete.
KKS® POLYMAD 720 complies with ASTM C494 type G.
KKS® POLYMAD 720 combines all different impacts through absorbed process on the surface of fine particles and keep it apart from each other in cement hydration processing:
• Easy to apply, without stratification.
• Flow-able concrete.
• Early strength and ultimate strength are high.
• High bearing capacity.
• Highly improved waterproofness.
• Increased volumetric stability, minimizing the risk of shrinkage.
• KKS® POLYMAD 720 is chloride free and other corrosive substances. Therefore it can be used in most .of the reinforced and pre-stressed concrete structures.
KKS® POLYMAD 720 is mainly suitable for production of concrete in precast concrete plants and in construction sites:
• Concrete required low water content.
• Flow-able concrete.
• High durability concrete.
• High strength concrete.
• Bridge concrete or cantilever erection.
• Mass concrete.
Dosage: 0.7 – 2.5 liters/ 100 kg of cement
Typical dosage: 0.8 – 1.2 liters/ 100 kg of cement
KKS® POLYMAD 720 is possible to combine with all KKS’s concrete admixture products, but it must be added separately to the mix. KKS® POLYMAD 720 is compatible with all Portland cement including sulfate resistant cement.
KKS® POLYMAD 720 is added to the gauging water prior to its addition to the dry mix or added separately to the wetted concrete mix.
For optimum utilization of the ultra-high range water reducer we recommend a wet mixing time of 2-3 minutes.
When adding the balance of the batching water to adjust concrete consistency this should be done after a minimum of 2/3 of the wet mixing time to avoid surplus water in the concrete.
PLACING OF CONCRETE
With the use of KKS® POLYMAD 720, concrete of highest quality is being produced, it should be complied and applied with standard procedures, such as mixing, placing vibrating and curing must be respected and applied.
APPLICATION CONDITIONS/ LIMITATIONS
Overdosing will result in increased workability and setting time of the concrete; however, provided that curing is effective, ultimate concrete strength and properties will not be affected.
Use an appropriate concrete mixer and do not mix by hand.
Trials mixes are recommended to establish exact dosage rates required to suit individual requirements. Please contact KKS Technical Department for further assistance.
Effective measures for concrete curing must be followed.
