Concrete Admixture
A range of liquid admixtures including superplasticisers, retarders, and accelerators for concrete.
Concrete admixtures are substances added to concrete mix to modify its properties, improving performance or achieving specific characteristics.
Specification of Concrete Admixture
| Specification | Parameter |
|---|---|
| Chemistry | PCE based, SNF based, or specialty |
| Solid Content | 30% to 40% (varies by grade) |
| Appearance | Brown or amber liquid |
| Chloride Content | Less than 0.1% |
Applications
Water Reducers
Reduce the amount of water needed while maintaining the workability of the concrete, which improves strength and durability.
Retarders
Slow down the setting time of concrete, useful in hot weather or when delays are expected.
Accelerators
Speed up the setting and curing process, often used in cold weather to ensure faster strength gain.
Air-Entraining Agents
Introduce tiny air bubbles into the concrete, which enhances its resistance to freeze-thaw cycles and improves workability.
Corrosion Inhibitors
Protect steel reinforcement within the concrete from corrosion, extending the lifespan of the structure.
Hydration Control Admixtures
Manage the hydration process to extend the working time of the concrete mix.
Coloring Agents
Provide aesthetic finishes by coloring the concrete.
Viscosity Modifiers
Adjust the flow properties of the concrete to enhance stability and reduce segregation.
