Product Description

BT-303 Polycarboxylate Superplasticizer
50% (High slump retaining type)
Product introduction
BT-303 is a new generation of slow releasing and slump retaining mother liquor made from TPEG by free radical polymerization, and a new sustained-release group is introduced into the synthesis. Under the alkaline condition of concrete, the slow-releasing group in the molecular structure of this product can slowly release the group with dispersive function, playing the role of continuing to disperse the cement, so as to achieve the role of inhibiting the concrete slump loss.It has a low water reduction rate, but it has very high slump protection performance. It is mainly used in high-strength concrete with higher requirements for slump protection performance, and its products are widely used in pumping concrete, super-flow self-compacting and high-strength high-performance concrete and commercial concrete for high-speed railway, expressway, hydro-power and other large engineering projects.


Product Feature
1.With super high slump performance, can let the concrete slump 2h without loss

2.Low water reduction rate is generally not used alone, it needs to be combined with water reduction type mother liquor.

3. With low viscosity and thixotropy, it is more suitable for concrete with low water cement ratio

4.The release time is slower than that of BT-302, generally after 1 hour (with the change of concrete material, there will be Certain fluctuations).

How to use

1.This product is a colorless or light yellow liquid. Dosage:Usually ,use 0-30% mother liquor with reducing water mother liquor, and mix other small materials to make water reducing agent. The dosage of water-reducing agent is generally 1% ~ 3% of the total weight of cementing materials.
2.Before use of this product or changing the type and batch of cement and gravel, it is necessary to carry out adaptability test with cement and gravel. According to the test, formulate the proportion of water reducing agent
3.This product can be single used(Usually it could not use in single) It can be combined with water-reducing mother liquor and set retarding mother liquor to reduce concrete slump loss. Or compound with functional aids to get admixtures with retarder/early strength/antifreeze/pumping functions. The application method and conditions should be determined by testing and compounding technology
4.This product can be used together with other kinds of admixtures such as early strength agent, air entrainment agent, retarder, etc., and should be tested before use. Do not mix with naphthalene series water reducer.
5. To achieve optimal results with your concrete cement, ensure the mix ratio is determined through rigorous testing. During application, it's crucial that the mixed and measured water is incorporated simultaneously with the concrete mixer. Prior to actual usage, conduct a comprehensive mixing test to ascertain the supreme quality of your concrete mixture.
6. In instances where active admixtures like fly ash and slag are part of the concrete mix, calculate the water-reducing agent based on the entire quantity of cementing materials. This ensures a balanced and efficient mix.
