Expanplast SP430R is a high-performance superplasticising admixture developed for concrete applications requiring high early strength, improved workability, and reduced water demand. It is a chloride-free, brown liquid formulation that disperses fine particles within the concrete mix, allowing the available water to work more effectively and improving cement hydration.
The product is particularly suitable for precast concrete, high-early-strength concrete, high-workability concrete, and applications in hot climates. It can significantly improve workability without increasing water content and can contribute to improved durability by increasing ultimate strength and reducing concrete permeability.
Key Features & Benefits
- High-performance superplasticising admixture
- Chloride-free formulation
- Helps achieve higher early and ultimate concrete strength
- Reduces water-cement ratio without sacrificing workability
- Improves workability and pumpability
- Helps minimize segregation and bleeding
- Suitable for precast and high-workability concrete
- Particularly suitable for hot-weather applications
- Compatible with Portland cements and cement replacement materials including PFA, GGBFS, SRC, and silica fume.
Technical Information
- Appearance: Brown liquid
- Specific gravity: Typically 1.18 at 20°C

Highly flexible, non-staining joint sealant with excellent recovery
DESCRIPTION
Polyseal PS GG is a non slumping two component,
chemically curing polysulphide joint sealant. Polyseal PS
GG is specifically designed to be used as a watertight seal
for moderate movement and control joints. It is based on
a liquid polysulphide polymer which when mixed with the
hardener, cures to form a tough, flexible and non staining
rubber like seal. Polyseal PS GG has excellent adhesion
to concrete, stone, metals and other common building
substrates. The cured sealant has good resistance to
most environmental chemicals & resists deterioration on
prolonged exposure to UV. Polyseal PS GG is suitable for
use in both vertical and horizontal applications. The sealant
has a movement accomodation factor (MAF) of ±25%.
