SPF-101 Polycarboxylic Acid High Efficiency, Pumping Agent

SPF-101 is an environmentally friendly and efficient pumping agent composed of SPF-300 and other polycarboxylic acid high-performance water reducing agent, which has extremely high water reduction performance and excellent slump retention, and can significantly reduce the viscosity of low water-to-adhesive ratio concrete, thereby improving the pumpability and constructability of concrete, and can greatly improve the early strength of concrete.

This product can be widely used in ordinary concrete, pumped concrete, super-fluid self-compacting and high-strength and high-durability concrete, especially in ultra-high pumped concrete and low water-to-adhesive ratio concrete construction applications have excellent performance.

Product Features

• High water reduction rate: excellent dispersion and water reduction rate of up to 25%.

• Excellent slump retention: excellent slump retention, good slump retention performance, can well extend the transportation time of concrete and the residence time of the construction site, especially in low slump retention.

• Good workability: It can significantly reduce the viscosity of concrete and improve the workability of concrete, thereby improving the pumping construction performance of concrete.

• Good dispersibility: Significantly improve the rheology of concrete, easy pouring and compacting, thus reducing construction costs.

• High strength growth rate: Higher strength growth rate with high early strength growth rate, improved shrinkage performance and reduced carbonization rate of concrete.

• Wide range of adaptability: very wide adaptability, all kinds of Portland cement, ordinary Portland cement, slag Portland cement and various admixtures have good dispersion and plasticity.

• Excellent durability: Low porosity, low alkaline content and chloride ion content can improve the durability of concrete.

• Green environmental protection: no formaldehyde and other harmful ingredients.

Scope of application

• Suitable for ready-mixed and cast-in-place concrete in a variety of industrial and civil buildings.

• It is suitable for all kinds of infrastructure projects such as water conservancy, offshore engineering, ports, transportation, bridges, subways, electric power, etc. that have high performance requirements for concrete. 

• It is especially suitable for special concrete such as high strength and high performance, high durability, super-fluid self-compacting, as well as ultra-high elevation pumped concrete, precast concrete, and long-distance transportation concrete.

Technical Note

• The main chain of polycarboxylic acid high-performance water reducing agent molecules is firmly adsorbed on the surface of cement particles, which can effectively hinder the hydration reaction and improve its plasticity, and the branch chain is surrounded by cement particles, playing the dual role of steric hindrance and electrostatic repulsion, which is completely different from the mechanism of dispersing cement particles by electrostatic repulsion of traditional water reducing agents, so it has better dispersion capacity and water reduction effect, and finally makes a qualitative leap in the comprehensive performance of concrete products.
