SikaPlast®-900 is a versatile “Building Trust” solution designed to meet the demands of modern concrete construction. By utilizing advanced polycarboxylate technology, this liquid admixture acts through surface absorption on cement particles, creating steric hindrance and electrostatic repulsion. This process results in superior dispersion, flow, and workability retention without requiring additional water. Primary Applications This admixture is highly effective for a wide range of structural elements and concrete types, including: Structural Elements: Slabs, foundations, walls, columns, piers, and piles. Infrastructure: Bridges, cantilever structures, and pre-stressed concrete. Performance Concrete: High flow, high strength, and concrete requiring substantial water reduction. Key Benefits and Characteristics Workability & Finish: Significantly improves workability and surface finish while increasing density and water tightness. Safety & Durability: Contains no chlorides or corrosion-promoting ingredients, making it safe for reinforced and pre-stressed steel. Reliability: Offers a low risk of segregation and maintains a normal set without unintended retardation within dosage limits. Compatibility: Can be used with all Portland cement types and integrated with other Sika products such as SikaPump, SikaFiber®, and Sika® FerroGard®-901. Technical Information Appearance: Brown liquid. Recommended Dosage: Typically 0.8–2.0% by weight of binder. Compliance: Meets the requirements of ASTM C494 Type G and EN 934-2. Storage: 12-month shelf life when stored in original packaging between 5C and 45C .Usage Note: SikaPlast®-900 should be added to the gauging water, never directly to dry cement. A minimum wet mixing time of 60 seconds is recommended for optimum performance
