      HUAXUAN HIGH TECHNOLOGY® KH-204
      Is a new version high-performance polycarboxylic superplasticizer. Compared with other high efficiency water-reducing agents,it has the properties of ultra-high water reduction,low shrinkage,low bleeding rate and small avalanche loss.

      Ultra-high water reducing rate:up to 40%,particularly significant in high-grade concrete (above C50).In the same condition,it costs less material to get the same effect.
Excellent plastic retention:
      Excellent plastic retention performance: Because the steric hindrance of the extended polymer side chain effectively hinders the secondary agglomeration between cement particles, the product has high dispersion and can maintain this performance for a long time.
      Good early strength and strengthening effect: under the same conditions, the concrete mixed with this product has a higher early strength and strengthening effect than other types of superplasticizers.

      Significantly improve the durability of concrete: The product has a low alkali content, and because it’s an air-entraining type high efficiency water reducing agent, it significantly reduces the alkali-aggregate reaction of concrete and improves the freeze-thaw resistance of concrete.

      HUAXUAN HIGH TECHNOLOGY® KH-203
      Is a polycarboxylic superplasticizer developed by HUAXUAN HIGH TECHNOLOGY® specially for precast concrete.Through the research on the structure, properties and functions of polycarboxylic acid water-reducing agent and the reasonable design of molecular structure, the product has the characteristics of high water reduction, viscosity reduction, low air entrainment, and early strength to meet the requirements of precast concrete.

      High water reducing rate:According to the national standard GB 8076-2008 "Concrete Additives", the water reduction rate can up to 50%.

      Viscosity reduction: by selecting suitable adsorption groups, adjusting the density and distribution of the adsorption groups, the water reducing agent molecules can be adsorbed quickly and dispersed efficiently.Thereby,it reduces the plastic viscosity of the cement paste and the yield stress of the concrete and solve the problems of stickiness, weight, and hardening of the high-grade concrete of the precast concrete,and highly improving the working performance.

      Low air-entraining: With the help of expertise of Geochemistry,we studied the relationship between the structure of the poly-based water-reducing agent and the air-entraining.Then we optimize the molecular side chain of the water-reducing agent, and adjust the lipophilic balance value of the water-reducing agent to optimize its space in the community.The size and stability make the internal structure of the center more compact and meet the structural requirements of prefabrication technology.

      Early strength: By adjusting the length of the side chain of the water-reducing agent and selecting a large molecular weight polymerizer, and compared with the ordinary water-reducing agent, the cement hydration speed can be increased to enhance the solid strength of the precast material, in the meanwhile,the joint strength does not shrink.

      Application:
      It’s suitable for pipe piles, pipe segments, track slabs, prefabricated buildings,other manufacturers to produce pipe piles, track slabs, beams, slabs, columns and other prefabricated components of high-grade concrete.
