Introduction of Early Strength Type Polycarboxylate Superplasticizer Liquid

Polycarboxylic acid high-performance water-reducing agent (early-strength type) is an early-strength high-performance water-reducing agent independently developed by our company. The main component of this product is synthesized using new polyether monomers through molecular structure design and grafting processes. A kind of early-strength polycarboxylic high-performance water-reducing agent compounded with other functional production additives. The use of this product can significantly reduce the water-cement ratio, improve the working performance of concrete, and make the concrete have high density and volume stability. properties, the use of this product can promote the development of early strength of concrete, shorten the steam curing time of concrete or even eliminate the steam curing link, thereby greatly improving production efficiency and saving energy consumption, and can significantly improve the early, mid-term and late strength of concrete.

Polycarboxylic acid high-performance water-reducing agent (early strength type) is suitable for the concrete precast component industry, such as the concrete pipe pile industry, prefabricated concrete precast components, and other concrete precast components.

Features of Early Strength Type Polycarboxylate Superplasticizer Liquid

High water reduction rate: Within the commonly used dosage range, the saturated water reduction rate can reach 40%.

High workability: It can effectively increase the fluidity of concrete, reduce bleeding and segregation, thereby improving the workability of concrete, making it easier to construct and compact. The resistance during pumping construction is small and easy to transport.

Early strength performance: The 1d, 3d, and 7d compressive strengths of concrete prepared with polycarboxylic acid high-performance water-reducing agent (early strength type) can be increased by more than 90%, 80%, and 65% compared with the benchmark concrete.

High durability: Increase the density of concrete and significantly improve the impermeability, frost resistance and carbonation resistance of concrete.

Low shrinkage rate: The 28-day shrinkage rate of hardened concrete is 20% lower than that of the second-generation water-reducing agent, which can significantly reduce the shrinkage of concrete and improve the volume stability and durability of concrete.

Strong adaptability: good compatibility with various cements, fly ash, slag and other admixtures.

Good stability: no stratification, no precipitation during long-term storage, and no crystallization in winter.

High economy: It can reduce the cement consumption by 20% and reduce the comprehensive project cost.

Green and environmentally friendly: non-toxic, non-irritating, non-radioactive, non-flammable and non-explosive dangerous goods, and will not cause corrosion of steel bars.

Instructions for Using Early Strength Type Polycarboxylate Superplasticizer Liquid

1) Depending on the type, dosage and water-binder ratio of cement, it can be adjusted by changing the dosage. The recommended dosage of this product is 2.0%.

2) When this product is mixed with other admixtures, its compatibility and adaptability must be checked first. When replacing admixtures, pay attention to cleaning the storage utensils.

3) After applying this product, the exposed surface of the concrete should be covered with heat insulation, and watering and curing should not be allowed when temperatures are below zero.

4) If there are special requirements for this product, our company can adjust it according to customer materials and requirements.

5) This product is a chemical safety product, but be careful not to accidentally eat it during transportation and use, and avoid contact with the skin and splashing into the eyes. Once this occurs, please rinse with plenty of water and seek medical treatment if necessary.

Applications of Early Strength Type Polycarboxylate Superplasticizer Liquid

Cold Weather Construction: In winter or cold climates, accelerating the setting and strength gain of concrete is crucial to ensure rapid curing and early form removal.

Accelerated Bridge and Road Repairs: For quick repairs and rehabilitation of infrastructure, early strength superplasticizers allow for faster reopening of traffic lanes.

Prefabrication Plants: In precast concrete operations, rapid strength development enables quicker turnover of molds and faster production cycles.

Emergency Construction: During emergencies or urgent construction projects, early strength gain ensures that critical structures can be put into service sooner.

Tunneling and Underground Works: In tunneling, early strength concrete can be used for shotcrete linings and other applications where quick setting is necessary for safety and progress.

High-Performance Concrete: For high-strength concrete applications where early strength is a requirement, these admixtures are indispensable.
