Product Description

Concrete Viscosity Modifiers RH-430

RH-430 is a new type of reaction synthesized macromolecular polymer solution. It can effectively improve the working performance of fresh concrete and make the viscosity of the mix reach a good balance between fluidity, passability and anti-separation.

Product characteristics

(1) RH-430 contains water-soluble polymers that modify the rheology of the mixture, optimizing stability by adjusting the slurry viscosity.Adjusting paste viscosity for optimum stability.

(2) It improves the flow and stability of concrete by improving the properties of the concrete paste rather than increasing the amount of cementitious material.

(3) The performance benefits are especially noticeable when using manufactured sand, ultra-fine sand and discontinuously graded coarse aggregates.

Recommended dosage: Generally 0.2%~2% of the amount of admixture, according to the type of raw material and the demand for appropriate mixing to determine the appropriate dosage.
 

Scope of application

1. Self-compacting concrete
Segregation may occur when the self-compacting concrete mix with less powder content is not affected by moisture changes.Adding viscosity-modifying admixtures to self-compacting concrete increases the resistance of concrete to segregation and improves the robustness of concrete to moisture changes.

2. Pumped concrete
In pumped concrete, aggregate blockage at the bend of the pipe is the most common problem.Adding modified admixtures can improve the viscosity of pumped concrete and prevent pumping segregation.

3. Underwater concrete
In case of underwater concrete, the concrete must have a high viscosity to prevent scouring during underwater construction. To prevent flooding, modified viscosity admixtures are added to underwater concrete to improve the cohesiveness of the mix. Therefore, it can also be called an anti-scouring admixture. It also increases the durability of underwater concrete structures. Generally, when concrete is placed underwater, the water becomes turbid due to cement dust generated by the concrete. But when RH420 are used, dust is not generated and the water remains transparent, which will make the concrete easier to place.
 

4. Prevents segregation and seepage of concrete.

 

5. Reducing the sensitivity of concrete to fluctuations in water use.

Usage and Precautions

1. When using, need to be mixed with other dry powder components together, when using according to the construction of different areas of mixing requirements for mixing and construction;
2. The recommended dosage isGenerally 0.2%~2% of the amount of admixture, and the specific dosage is determined by trial mixing according to the application system and the change of dry mix components;

packaging and storage

1. 200 kg plastic drums and 1000 kg IBC tonne drums, the storage period is 12 months from the date of production, if it exceeds the shelf life, it must be verified by test and inspection before use;
2. Place in a ventilated and dry place for storage, pay attention to moisture-proof treatment, avoid direct sunlight, use it in time after opening, and seal it in time if it is not used up to prevent moisture absorption and deterioration
