Description and advantages
-
Polycarboxylate superplasticizer (PCE) is an advanced chemical additive used in the construction industry to enhance the performance of concrete.
-
As a new generation of high-performance superplasticizer, this superplasticizer is developed after the common water reducing agent represented by wood calcium and the high-efficiency superplasticizer represented by naphthalene series.
-
At present, PCE is a superplasticizer with the best application prospect and the best comprehensive performance. So it can be widely used in highways, bridges, dams, tunnels, high-rise buildings, and other projects.
Applications
-
PCE superplasticizer is suitable for long-distance concrete pumping.
-
For the preparation of ordinary concrete, high-performance concrete, high-strength concrete, ultra-high-strength concrete.
-
Formulate durable concrete with impermeability, high moisture retention and freeze-thaw resistance requirements.
-
This product can prepare high fluidity concrete, self-leveling concrete, fair-faced concrete and vibration-free self-compacting concrete.
-
The polycarboxylate admixture is also used to configure various concretes with high fly ash and mineral powder.
-
The recommended dosage range of polycarboxylate superplasticizer is 0.3% - 0.5%, and the dosage range can be adjusted appropriately for special cement or aggregate.
-
It can be mixed into the metered water and added to the concrete mixer at the same time with water. In order to achieve a good water reduction effect, we recommend that the mixing time is at least 150s.
-
When using this product for the first time or changing the cement type, the necessary trial mixing test should be carried out according to the site raw materials and construction conditions, and the mixing amount and construction mixing ratio should be determined according to the test results to ensure the quality of the concrete.
-
Due to the high water reduction rate of PCE superplasticizer, its concrete slump is very sensitive to the water consumption, and the water consumption and dosage must be strictly controlled during use.
-
Polycarboxylate based superplasticizer should not be mixed with naphthalene, melamine, amino and other water reducing agents, otherwise the performance index will be significantly reduced.
- The instructions for construction and use of products provided by our company are based on science and will be useful information when the company's products are properly stored, handled and constructed under normal conditions within the limits of product lifespan.
- We do not include responsibility for supervision of construction should use the product according to bmq's instructions, however it must comply with the changes and adjustments of the engineer investor or the constructors in each specific environment.
