NC-F002 Polycarboxylic Acid High Efficiency Water Reducing Agent
(For Precast Concrete)
NC-F002 is an environmentally friendly and efficient water reducing agent composed of NC-F001 polycarboxylic acid high-performance water reducing agent, the product has extremely high water reduction performance, low air entrainment, after use can greatly improve the early strength of concrete and make the hardened concrete have good appearance quality. It can be widely used in various precast beams, slabs, columns, pipe piles, segments, prestressed members and other concrete pre-products. It can also be widely used in steam-curing concrete.
Product Features
- Extremely high water reduction rate: excellent dispersion can provide a strong water reduction effect, the water reduction rate is as high as 40%, which provides a guarantee for improving the working performance of concrete, increasing the strength of concrete and saving cement.
- High strength growth rate: extremely high strength growth rate with high early strength growth rate, improved shrinkage performance and reduced carbonization rate of concrete.
- Low slump retention: For concrete with low slump, the slump loss is not more than 20% for 1 hour.
- Good adhesion: It has good adhesion to concrete, so that concrete has good workability, no delamination, no segregation, no watercretion.
- Excellent durability: Low shrinkage, low alkali content and chloride ion content can improve the durability 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.
- Green environmental protection: no formaldehyde and other harmful ingredients.
Scope of Application
- It is suitable for precast concrete in various industrial and civil buildings.
- It is especially suitable for various infrastructure projects with high performance requirements for concrete, such as railways, water conservancy, offshore engineering, ports, transportation, bridges, subways, and electric power.
- It is suitable for special concrete such as high strength and high performance, high durability and steel fiber.
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.
