Superplasticizer Polycarboxylate Concrete Admixture

Description

Superplasticizer Polycarboxylate Concrete Admixture is polymerized by various macromolecule organic compounds. This superplasticizer belongs to polycarboxylate-based grafted copolymer superplasticizer, and is a new generation of environment friendly cement admixture of advanced world level. 

The polycarboxylate-based superplasticizer (PCE-SPC) has reached the international advanced level on the aspects of technical performance index and cost performance.

The PTMA-PCE -SPC can be widely used in water conservancy project, electrical power project, port project, railway project, bridge project, highway project and main structure cement casting of civil building.

Performance

1. High Water reducing Rate: Water-reducing rate of mortar can reach above 20%, and the fluidity of mortar can be greatly improved when adding the same amount of water.

2. High Early-Strength: it improves the early strength and the limit strength of the mortar.

3. High Durability: it  reduces the water-binder ratio, and enhance the durability perform-ance, decrease the shrinkage and creep deformation and reduce shrinkage crack at the last stage of the mortar hardens.

4. Environment Friendly Product: No pollution is caused to natural environment during the production; totally meet the international standard of ISO 14000 Environment Protection Management.

Applications

PTMA-PCE-SPC is a special polycarboxylate-based superplasticizer for dry mortar. It has a good adaptability with cement and other admixtures and has been widely used in non-shrinkage grouting material/mechanical grouting material, repair mortar, cement-based mortar, waterproof mortar, crack-sealer and thermal mortar, and other cement-based dry powder material. It has been proved to be very helpful in improving the fluidity, early and final strength and the decreasing the shrinkage crack at the last stage of the mortar hardens. Besides, the product is applicable to the gypsum-based dry powder material, fire-proof material and ceramics.

Recommend Mixing Dosage 

The recommended range of dosage in various powder materials shall be accounted of 0.2-0.3% of cementing material.

Package & Storage & Transportation

1. The package is 25 kg bag.

2. Large or special package are also available for customer demands.

3. Store in a dry place with a normal temperature (below 40?), no stacking or great pressure to avoid caking products.

4. Be kept for 12 months in the original package, and it shall be put in use within 60 days in case of opening the original package.

5. Shall be transported according to the standard of common chemical products.
