SP 888
High-Performance Superplasticizer for Self-Compacting Concrete

SP 888 is a new generation of superplasticizer admixtures based on polycarboxylate ether technology. This product is designed for high early strength and long slump retention, making it ideal for concrete production in hot weather or for long-distance transportation, while achieving high strength performance.

Mechanism of Action:
SP 888 prevents the accumulation of cement particles by creating electrostatic repulsion between particles through similarly charged ions. Additionally, it forms a shell around the surface of cement particles and causes steric hindrance, resulting in maximum dispersion efficiency.

Applications:

• Pumped concrete

• Self-compacting concrete (SCC)

• Underwater concrete

• Industrial flooring concrete

• Concrete containing silica fume, fly ash, slag, and other additives

Standards:

• ISIRI 2930 – Tables 12/13

• EN 934-2 – Tables 11.1/11.2

• ASTM C494 – Type G

Physical and Chemical Properties:

• Chemical composition: Copolymers of polycarboxylic acid

• Color: Light brown

• Specific gravity (g/cm³): 1.05 ± 0.02

• Chloride content (ppm): Negligible

Dosage:
Recommended dosage is 0.4% to 1.4% of the cement or cementitious materials weight.

Packaging:
SP 888 is available in 20-gallon containers, 220-liter drums, and 1100 kg tanks.
