Polycarboxylate Superplasticizer is a kind of concrete admixture; it is the third generation of high-performance water reducing agent after lignosulfonate, naphthalene sulfonate, melamine and amino sulfonate; it is a macromolecular compound with sulfonate, carboxylate, hydroxyl, ether bond and polyoxyethylene side chain, synthesized in aqueous solution through the principle of radical polymerization and has the advantages of high water reduction, excellent maintenance of loss of caving degree and better adaptation to cement.
Polycarboxylate Superplasticizer has the advantages of a high water reduction rate, excellent loss of caving degree and better adaptability to cement, etc. Polycarboxylic acid water reducing agent has no process wastewater and waste gas in its production process, which belongs to the green, environmentally friendly materials. The molecular structure can be adjusted, which has become an important direction for the development of concrete water reducing agent in the future, and the application of it in the modern concrete project is becoming more popular day by day.
Under conditions where the slump of concrete is the same, it can significantly reduce the amount of water used in mixing or significantly improve the fluidity of concrete under conditions where the amount of water used is the same. Polycarboxylate superplasticizer is widely used in railway, rail transit, and other building concrete. With the development of polycarboxylic ether superplasticizer, Polycarboxylate Superplasticizer Monomer are necessary raw material carriers for producing polycarboxylate water reducers.
Concrete must have good pumping performance and workability to ensure smooth construction in high-rise buildings.
Polycarboxylic ether Superplasticizer can meet these requirements and improve construction efficiency and quality.
Bridge engineering requires high strength and durability of concrete, and polycarboxylate superplasticizers can improve the strength and durability of concrete, ensuring the safety and reliability of bridges.
The underground engineering environment is complex, and strict requirements are placed on the impermeability and durability of concrete.
Polycarboxylic ether Superplasticizer can improve the impermeability and durability of concrete, ensuring the long-term stability of underground engineering.
The production of prefabricated components requires concrete to have good workability and early strength performance.
Polycarboxylate superplasticizers can meet these requirements and improve the production efficiency and quality of prefabricated components.
In fields that require high-performance concrete, such as marine engineering, nuclear industry, etc., the application of polycarboxylate superplasticizer can further enhance the performance of concrete and meet the requirements of special environments.
It is suitable for ready-mixed and cast-in-place concrete in various industrial and civil buildings, especially for all kinds of water conservation, harbour, transportation, subway, electric power, and other infrastructure projects that have high concrete requirements.
Reduce water consumption: Low dosage of polycarboxylate superplasticizer can significantly reduce the water-cement ratio of concrete, thereby reducing water consumption. This helps save water resources and reduces the drying shrinkage and permeability of concrete, improving its durability.
Improving workability: After adding polycarboxylate ether superplasticizer, its applicability to cementitious materials such as cement is good. The flowability and plasticity of concrete are significantly improved and maintained, making it easier to carry out construction operations such as pumping and vibration. This is very advantageous for the construction of complex structures and large-scale projects.
Enhanced strength: Polycarboxylic ether Superplasticizer can effectively disperse cement particles, making concrete denser and thus improving its stability. At the same time, it can also reduce pores and cracks in concrete, further improving strength and durability.
Improving durability: Polycarboxylate superplasticizers can reduce the water-cement ratio, porosity, and shrinkage rate of concrete, improving its impermeability, frost resistance, and chemical resistance and extending the service life of concrete structures.
The dosage of polycarboxylate superplasticizer is generally 0.25%~1.5% of the weight of the cementitious material, and it must be tested in the laboratory of concrete mixtures.
Secondly, the optimal dosage can be adjusted within the recommended range according to the adaptability to cement, climate changes, and concrete slump requirements.
When mixed with other additives, compatibility tests should be conducted in advance. Do not use it in combination with naphthalene-based water-reducing agents. Slump retention is sensitive to moisture, and the moisture content should be strictly controlled.
It can be given attention when curing concrete. Generally speaking, the water reduction rate of polycarboxylate superplasticizer can reach about 30%.
Mixing in a concrete mixer for at least 150 seconds is recommended to achieve a good water reduction effect.
