Polycarboxylate Ether Superplasticizer Pce

Polycarboxylate ether superplasticizer pce

Product Description

Polycarboxylate superplasticizer is a new generation of environmentally friendly superplasticizer independently developed by our company. The liquid is light yellow or brown-red transparent liquid. The main component is a series of polycarboxylic acid polymer products with a molecular weight of 5000-50000. The performance comparison with similar products at home and abroad shows that the polycarboxylate superplasticizer has reached the international advanced level in terms of technical performance indicators and cost performance. It is a series of superplasticizers with excellent performance that integrates water reduction, slump protection, reinforcement, shrinkage resistance and environmental protection. It can completely solve the weaknesses of high-strength and high-performance concrete with high viscosity and poor construction performance. , Ideal admixture for high performance concrete. It can be compounded with various admixtures to form multifunctional admixtures, such as pumping agent, early strength agent, impermeable waterproofing agent, retarder, etc.

Product Main Performance

The superplasticizer has the following effects in improving the characteristics of concrete: 

(1) It can reduce the water demand of the concrete. Or it can improve the swimming degree of the concrete without increasing the water demand. 

(2) The initial setting time of concrete can be adjusted. 

(3) Reduce bleeding and segregation. Improve workability and resistance to water washing. 

(4) It can reduce slump damage and improve the pumpability of pumped concrete. 

(5) It can reduce the shrinkage. The expansion agent is added to compensate for the shrinkage. 

(6) Slow down the hydration heat of concrete in the early stage. Reduce the leakage current rate of mass concrete and reduce the generation of gaps. 

(7) Improve the initial strength of concrete. Avoid freezing under negative temperature.

 (8) Improve strength, improve cold resistance, waterproof concrete, abrasion resistance and corrosion resistance. 

(9) Use the alkali-stone reflection to prevent the rust of the rigid bars and reduce the spread of chloride ions.

(10) Concrete with other unique characteristics. 

(11) Reduce the viscosity coefficient of concrete, etc.

Technical indicators

Instructions for use

1. The dosage of polycarboxylate superplasticizer is 0.4 percent to 2.5 percent of the total weight of the cementitious material, and the usual dosage is 0.8 percent to 1.5 percent . Concrete trial mix test should be carried out before use in order to obtain the best dosage.

2. Polycarboxylate superplasticizers cannot be mixed with naphthalene-based superplasticizers. When using polycarboxylate superplasticizers, the mixers and mixer trucks that have used naphthalene-based superplasticizers must be rinsed clean, otherwise they may be lost. Water reduction effect.

3. When using polycarboxylate superplasticizer, it can be added directly in the form of stock solution, or it can be used in a certain concentration solution, and the water amount brought in by HK-1 polycarboxylate superplasticizer itself is deducted.

4. Due to the high water reduction rate of concrete mixed with polycarboxylate superplasticizer, the slump is highly sensitive to water consumption, and water consumption must be strictly controlled during use.

5. Polycarboxylate superplasticizer has good adaptability with most cements, but may have low water reduction rate and large slump loss for individual cements. In addition, the fineness and storage time of cement may also affect the use effect of polycarboxylate superplasticizer. At this time, it is recommended to solve the problem by appropriately increasing the dosage or compounding other retarding components. Or please contact us, we will solve it for you in time.

6. After adding polycarboxylate superplasticizer, the air content of concrete increases (usually 2 percent to 5 percent ), which is beneficial to improve the workability and durability of concrete. For other special requirements, please contact us, we will solve it for you in time.

7. Due to the small dosage of polycarboxylate superplasticizer and high water-reducing rate, the use of polycarboxylate superplasticizer to prepare various types of high-performance concrete above C45 can greatly reduce engineering costs and have significant technical and economic benefits. ; The cost of polycarboxylate superplasticizer for preparing concrete below C45 is high, but it can reduce the overall cost of concrete by increasing the amount of mineral admixtures, which also has certain technical and economic benefits.
