Sikament®-512 Star | MCT CHEMICALS | SIKA PAKISTAN

Sikament®-512 Star PK is a highly efficient water-reducing agent and superplasticizer, designed to produce high-quality, free-flowing concrete, particularly in hot climates. It is ideal for use in tropical and hot environmental conditions.

Uses: Sikament®-512 Star PK is suitable for applications requiring high-quality concrete, especially in challenging placement and climatic conditions.

Characteristics/Advantages: As a Superplasticizer:

• Significantly improves workability without increasing water content or causing segregation.
• Provides long-lasting slump loss control.
• Does not negatively impact ultimate strengths.

As a Water Reducer:

• Increases ultimate strength.
• Reduces water content by more than 15%.
• Particularly effective in hot climates.
• Prevents excessive air entrainment.
• Does not cause shrinkage issues.
• Enhances surface finish.
• Improves water tightness.

Approvals/Standards: Sikament®-512 Star PK meets the requirements of ASTM C494; Type G.
