Technical Performance of Powder Polycarboxylic Acid Water Reducing Agent

Polycarboxylate ether superplasticizer has good dispersibility and flowability for cement at low dosage; When the dosage is greater than 0.12% to 0.22%, there is a very significant increase in the fluidity of the slurry; The loss of fluidity of the slurry within 1 hour decreases with the increase of the dosage. The water reduction rate increases rapidly with the increase of the dosage, and the water reduction rate is relatively high; There is a corresponding relationship between the results of mortar water reduction rate and the results of net slurry fluidity, with both high net slurry fluidity and high mortar water reduction rate; The concrete water reduction rate of Pce Polycarboxylate Ether Superplasticizer is often inconsistent with the mortar water reduction rate due to the influence of additives and sand and gravel properties. When the properties of admixtures and sand are beneficial to the fluidity of concrete, the water reduction rate of concrete is higher than that of mortar, and vice versa, it is lower than that of mortar.

The characteristics of PCE Powder compared to traditional liquid polycarboxylate additive products:

1.Polycarboxylate Superplasticizer Powder can be widely used in building materials such as dry mix, ceramics, coatings, gypsum products, refractory materials, etc

2. Pce for Concrete facilitates long-distance transportation and reduces storage space

3. High water reduction rate: water reduction rate can reach 30%

4. Low dosage: 0.1%~0.3%

5. High early strength: the 3D strength of concrete can be increased by 100% -400%

6. Effectiveness under low water cement ratio: Under the condition of a water cement ratio of 0.15, high-strength concrete with high compressive strength can be prepared
