TDS of SPS-28 Water-Reducing High-Performance

PCE Flake

Description

SPS-28 is a new-generation, environmentally friendly, high-performance PCE powder characterized by high water-reducing and full water solubility.

Technical Principle

With EPEG-3000 as the main raw material, by optimizing the side chain conformation and conducting free radical copolymerization at low temperature, the efficient dispersion and stable slump retention were finally achieved through the synergistic effect of steric hindrance and electrostatic repulsion.

Advantages/Characteristics

l Solid content: 97% min.

l Rapidity and completely dissolved in water.(Completely soluble in water. If it is used for ready mix concrete or precast concrete, please add PCE flake to water to get a solution with solid content 20% or 10% before use ).

l High water-reduction rate and excellent adaptability to different types of cement and admixtures.

l Compatible with early strength agent, air entraining agent, defoaming agent, etc., supporting multi-functional composite applications.

l With a good slump retention ability, enhance cohesion, without concrete segregation.

l Having a thermostability to 50℃ (fifty degree celsius centigrade).

Application

Applicable to various concrete construction projects such as high-strength, self-compacting, and mass concrete, it significantly enhances construction efficiency and structural durability.
