About Superplasticizer Price
Do you know what is the superplasticizer?
Concrete superplasticizers are synthetic polymers used in the preparation of high-strength concrete. They are also known as high range water reducers, as their use in wet concrete allows the reduction of the water content in the wet concrete mix by up to 30%. Reducing the water-cement ratio is critical, as the low water content increases the strength of concrete.
Concrete superplasticizers also maintain the desired workability of the concrete mix and indirectly add strength to hardened concrete. The effect of concrete superplasticizers is very short. It only lasts 30 to 60 minutes, depending on the dosage rate. The short effect of concrete superplasticizers is quickly followed by a rapid loss of workability of the concrete mix. Thus, to avoid slump loss, superplasticizers are usually added to the concrete mix at the construction site.
Divided as follows according to constituent materials.
Polycyclic aromatic salts;
Water-soluble resin sulfonate.
High Performance Polycarboxylate Water Reducer is a high performance water reducer for concrete with the world’s most advanced technology, the highest technology content, the best application prospects and the best overall performance.
High Performance Polycarboxylic Acid Water Reducing Agents are a composite product of multi-element copolymers grafted with carboxylic acid and other effective additives. Performance comparisons with similar products at home and abroad show that high-performance polycarboxylic acid-based water reducing agents have reached the current internationally advanced level in terms of technical performance indicators and cost performance.
Polycarboxylic acid series High performance water reducing agent
- The amount of mixing is 0.5% to 2.0% of the total weight of cement-based material and the normal amount of mixing is 0.2% to 0.5%. A specific experimental mix test must be carried out before use to find the ideal mix.
Cannot be used in combination with high performance naphthalene-based water reducing agents. When used in combination with other additives, the suitability of the concrete must be tested in advance.
The Slump is very sensitive to water consumption and it is necessary to strictly control the water consumption during use.
Pay attention to the maintenance of the concrete surface.
There are also some problems with high performance polycarboxylate water reducing agents:
- Inadequate slump retention in high temperature environments;
If strong temperature sensitivity, the same high performance polycarboxylic acid water reducing agent is built in different seasons, the drop retention of concrete will be very different;
It is a functional product and it is difficult to meet the requirements of ultra-high and ultra-long range concrete pumps, negative temperature structure, ultra-initial strength concrete preparation and high concrete durability. Four. In the preparation of high viscosity, high mixing and low water adhesion rate concrete, concrete viscosity is high and not useful for construction.
High performance polycarboxylate reducing agents are suitable for precast and cast-in-place concrete, reinforced concrete and prestressed concrete in the construction of high speed railways, passenger lines, industrial and private buildings, roads, bridges, ports, airports, etc.
Especially suitable for projects with long construction times and high demand for concrete spines, such as nuclear power plants.
