Advantages
1.This product is produced by high active catalyst and special process, which makes it in light color appearance.
2.This product has good selectivity, high double bond retention rate, which can dramatically increase the yield of the water reducing agent products, thus reduce the production cost of the water reducing agents.
Characteristics
1. The polycarboxylate superplasticizer made from polyoxyethylene ether TPEG2400 has good adaptability to cements.
2. Compared with other polycarboxylate materials, the production cost of polycarboxylate superplasticizer made from polyoxyethylene ether TPEG2400 is greatly reduced.
3. The water reducing rate of the water reducer (solid content 22%) from this material is amount to 30% under 1.1% concrete addition.
4. The water reducer from this material is characterized by early strength, high-strength, the early strength and 28 days’ strength of the concrete is greatly improved, compressive strength ratio %: 1 Day ≥180; 7 Days≥170; 28 Days≥ 150.
5. The water reducer from this material has high durability,can efficiently reduce the water/gel ratio, enhance durability, reduce shrinkage and creep.
6. The water reducer from this material has less slump loss, which grows initially, and won’t influence the strength, it also has sustained release effect, slump retention is ≥190 mm.
7. The water reducer from this material is environment friendly, chloride ion is not more than 0.1%, comply with the ISO 14000 international environment protection management standard.
