Polycarboxylic acids are used as pumping agents CAS 62601-60-9
Polycarboxylate Superplasticizer:
Polycarboxylic superplasticizer powder is a powder polycarboxylic acid superplasticizer/superplasticizer prepared by special spray drying process, which is a new generation of environmental protection superplasticizer products with high water reduction rate, high plasticity and high temperature resistance. It is a high-performance admixture specially developed for the application of various cementing materials under high temperature conditions, which can still give the material system excellent constructability under high temperature conditions, while making the strength increase rapidly and stably. It is especially suitable for cement base and gypsum base materials and products with high flow requirements at higher than normal temperature conditions to achieve excellent performance and meet various application requirements.
The main components of the pumping agent are polycarboxylic acid water-reducing agent and auxiliary polyols and hydroxy-carboxylic acid modified components, which can meet the needs of long-distance transportation of commercial concrete with large mobility. The product has high water reduction rate, remarkable enhancement, appropriate air entraining and retarding effect. Almost no bleeding and other performance characteristics. After mixing, it can significantly increase the slump of concrete, improve the workability of mix, achieve the pump construction performance with less slump loss and good plastic protection effect, which is conducive to reducing the carbonation and shrinkage of concrete, and greatly prolong the service life of concrete. The technical and economic effects of the concrete prepared and pumped by this product are obvious. It can be widely used in all kinds of precast, pumping, long-distance transportation, fluid concrete, medium and high grade concrete and ultra-high strength concrete; Precast and cast-in-place concrete, reinforced concrete and precast reinforced concrete for industrial and civil construction of roads, Bridges, water conservancy, port terminals, airports, high-speed railways and other projects.

Product Features
(1) High water reduction rate: the product in the content of 015~03%(based on solid content), water reduction rate of 18~40%, can meet the needs of ultra-low water-cement ratio, high liquidity concrete, while saving cement 10~20%.
2) Low slump loss: Long side chains of macromolecules are introduced into the synthesis process of this product, which inhibits hydration on the one hand and provides steric hindrance on the other hand, so that the slurry can remain plastic for a long time and has good slump retention.
(3) Excellent workability: The concrete prepared with this product has good workability, no segregation, no stratification, good cohesion suitable for long-distance transportation and pumping.
(4) High durability: This product uses free radical aqueous solution polymerization, chloride ion content is very small, only a small amount of alkali neutralization, alkali content is very low, alkali content and chloride ion content is relatively stable, low chlorine and low alkali can greatly improve the durability of concrete.
(5) Low shrinkage and anti-cracking: this product can reduce the heat of hydration, delay the heat release peak, suitable for large volume concrete, can effectively reduce the cracking caused by the temperature difference of hydration of concrete.
(6) Green environmental protection: This product uses free radical aqueous solution polymerization, the raw materials do not contain formaldehyde and other pollutants, no sewage wastewater discharge in the synthesis process, ultra-low environmental load, belongs to the new green environmental protection building materials.
