SikaPlast 2120 GH – 5kg

Description

DESCRIPTION
SikaPlast- 2120 is a liquid admixture for concrete which is used as a mid-range water reducer/superplasticiser. It meets the requirement of BS EN 934 -2.

USES
SikaPlast-2120 is designed for use in both ready mix and precast applications whenever extended workability, high plasticity, and increased early/ultimate strengths are required. SikaPlast-2120 is mainly used for the following applications:

• Concrete that require high water reduction up to 25%.
• Applications that require high quality concrete.
• Applications that require improved consistence retention; Up to 2.5hours workability time possible.
• Concrete produced with very reactive cements.
• Precast application that require longer time during casting

FEATURES
SikaPlast-2120 works based on a mechanism of both electrostatic dispersion and steric repulsion effects.
Thus, solid particles can be effectively dispersed and a high level of fluidity can be reached with less water. As a result, SikaPlast-2120 can provide moderate workability time and stability than conventional dispersants Keeps workability for extended time, Slump retention without additional retarder and subsequent fast strength development high impermeability effect.
Mid-range water reductions resulting in higher strengths and densities

• Less sensitive to variations in cement and aggregate types
• Improved cohesion properties
• Improved early and ultimate strengths
• Improved rheology
• Improved durability
• Reduced segregation and bleeding
• Reduced drying shrinkage
• Reduced mix costs
• Compared to concrete without admixture

Recommended dosage 0.8 – 2.0 % by weight of cement (binder)
