PCE Polycarboxylate Superplasticizer Liquid High Range Water Reducing Admixture

JF POLYCARBOXYLATE SUPERPLASTICIZER Product Description:

Synonyms:Water Reducing PCE

Polycarboxylic acid water reducing agent is a high-performance liquid polycarboxylic acid high-performance dispersant specially used in high-aluminum and sulphur-aluminum cement systems. It is a white or light yellow liquid. It has very excellent dispersing ability, can significantly improve the fluidity of cement-based materials, and endow the material with excellent workability and high mechanical strength; it also has a very fast plasticizing speed, which can be used quickly after mixing with water It can significantly improve construction efficiency and meet different construction requirements.

Polycarboxylic acid high efficiency water reducing agent performance:

The content of chloride ion and alkali in polycarboxylic acid superplasfier is very low, and the surface tension is only 37.8mN/m, which can greatly reduce the surface tension of capillary in concrete void solution, reduce the drying shrinkage of concrete, and improve the durability of concrete. Through a large number of experimental studies, when poly carboxylic acid dosage is 0.15% of cement dosage, it has more than 20% water reduction rate, and its water reduction rate exceeds the level of general naphthalene system efficient water reducing agent on the market at present. When the amount of admixture increases, water consumption is reduced, water reduction rate increases and water reduction rate increase is not very large, but the slump retention ability tends to be more stable, new mixed concrete regardless of slump or expansion 1h is increased, but when the amount is too high, concrete will have a certain amount of bleeding.

The influence of PH value on polycarboxylic acid water reducing agent:

1. With the increase of PH value, the compressive strength ratio of concrete tends to increase slightly, but the strength does not change significantly at the later stage.
2. With the increase of PH value, the initial water reduction rate of concrete has no obvious change, but the slump and expansion of concrete decrease obviously after one hour of time loss.
3. With the increase of PH value, the gas content of concrete has no obvious change, but the viscosity of concrete increases and the flow velocity decreases.
4. With the increase of PH value, the compressive strength ratio of concrete increases slightly at age, but the strength does not change significantly at later stage.
