Admixture polycarboxylate superplasticizer

Polycarboxylate Superplasticizer is a high-performance water-reducing agent and a cement dispersant in the application of cement concrete. Widely used in highways, bridges, dams, tunnels, high-rise buildings and other projects.


Polycarboxylate based superplasticizer

Polycarboxylic acid series high-performance water-reducing agent is a new generation of water-reducing agent, which has become popular at home and abroad in recent years. Since it truly designs an effective molecular structure according to the mechanism of action of dispersed cement, it has a super-dispersed type, which can prevent the loss of concrete slump without causing obvious retardation. At low dosage, it can also exert a high plasticizing effect, and has good fluidity retention.



Polycarboxylate ether superplasticizer concrete

After adding water reducer to cement concrete, it has a significant reinforcing effect on concrete, can reduce concrete shrinkage, and endow concrete with excellent construction workability, good strength development, excellent durability, and polycarboxylate-based high-performance water reducer. It has good comprehensive technical performance advantages and environmental protection characteristics.


Polycarboxylate ether superplasticizer (pce)

Polycarboxylate superplasticizer is suitable for prefabricated and cast-in-place concrete, reinforced concrete and prestressed concrete in the construction of high-speed railways, passenger dedicated lines, industrial and civil buildings, roads, bridges, ports, airports, etc. It is especially suitable for projects with long construction time and high requirements for concrete slump, such as nuclear power projects.

The dosage range of polycarboxylate superplasticizer is generally 0.5-1.5% of the weight of the cementitious material when converted to 20% solid content, and the recommended dosage is 1.0%. Main features:

  1. Good compatibility with various cements, good slump retention performance of concrete, and prolong the construction time of concrete.

  2. Low dosage, high water reduction rate and small shrinkage.

  3. Greatly improve the early and late strength of concrete.


Polycarboxylate superplasticizer factory

There are generally three methods for the production of polycarboxylate superplasticizers:

  1. In situ polymerization grafting method

    Using polyether as a medium for the polymerization of unsaturated monomers, the main chain polymerization and the introduction of side chains are carried out at the same time, the process is simple, and the molecular weight of the synthesized water reducing agent can be controlled to a certain extent, but the esters involved in this method are The chemical reaction is a reversible reaction, and the grafting rate is relatively low when carried out in an aqueous solution, which has been gradually eliminated.

  2. First polymerization and then functionalization method

    This method is mainly to synthesize the main chain of the superplasticizer first, and then introduce the side chain for functionalization by other methods. This method is difficult to operate, the molecular structure of the superplasticizer is inflexible, and the compatibility between the monomers is not good, making it difficult to operate. The use of this method has been greatly restricted.

  3. Monomer direct copolymerization method

    In this method, the active macromonomer is prepared first, and then the small monomer and the macromonomer are copolymerized in an aqueous solution under the initiation of an initiator. As the synthesis process of macromonomers becomes more and more mature and there are more and more types, this synthesis method has become the most commonly used method for the synthesis of polyvinyl acid superplasticizers at this stage.
