The influence of sodium sulfate content on concrete:
1. If the content is large, it may crystallize at low temperature which blocks pipes and valves, and reduces the water reducing capacity and strength.Because the solubility is affected by temperature change.When the outdoor temperature is below 20ºC, the solubility will drop suddenly. When the outdoor temperature is below 16ºC, the crystal of sodium sulfate is obvious.During crystallization, some effective components of naphthalene series superplasticizer will be adsorbed, which will affect the water reducing ability and strength of concrete.

The effect of chloride ion content on reinforcement:
Chloride ion is the catalyst of corroded steel bar, which will not be consumed in the process of corrosion. If the content of chloride ion in the admixture is too high, it will accelerate the corrosion of steel bar and affect the strength of concrete

Benefits
1. Water reduction in concrete up to 18% - 20%.
2. Higher slump with lower water / cement ratio.
3. Flowable & pumpable concrete with improved rheology.
4. Homogeneous, honey comb - free, dense concrete.
5. High strength due to reduced water / cement ratio.

Application
 

Ready Mix Concrete
• Marine concrete
• Gunite concrete
• Architectural concrete
• Pre-cast and pre-stressed concrete
• In areas of congested reinforcement, where higher workability is of some advantage or benefit
• In reducing water content, for the sake of improving impermeability and durability.
