Types of High-efficient Water Reducer

Prices in the national electricity market averaged $87 per megawatt-hour in the first three months of the year, above the level promised by the federal government. Wholesale electricity prices for industry and large businesses have already exceeded the level promised by the federal government, adding another cost pressure to the economy. Prices in the national electricity market averaged $87 per megawatt-hour in the first three months of this year, up more than two-thirds from the December 2021 quarter, the Australian Energy Market Operator (AEMO) said recently. That's up 141% from the March 2021 quarter.

Because of the ever-changing international situation, the supply and prices of international bulk concrete water reducer are still very uncertain.

Types of High-efficient Water Reducers

Polycyclic aromatic sulfonates 

It has the advantages of low cost and high water reduction rate and has the defects of more serious collapse loss of mixing products. In use, you can add retarding components to compound use or choose such water reducer with sustained-release performance to reduce the loss of collapse and ensure the performance of high efficient water reducer. 

Water-soluble resin sulfonates 

Mainly for sulfonated melamine resin, and sulfonated ancient code long resin. This kind of water reducer and cement compatibility is better, and other water reducer mixed-use can also maintain good compatibility. Practice shows that this kind of water reducer has a low dosage but high water reducing rate and excellent performance. In a certain proportion, the water-reducing rate increases with the increase of water adding amount. Once the dosage exceeds the critical proportion, the retarding effect on concrete is obvious. Such plasticizer shall not be mixed with a lignosulfonate plasticizer. 

Aliphatic series

There are mainly polycarboxylic acid, polyacrylic acid salt. This kind of water reducer is different from traditional water reducer, so it is necessary to understand its mechanism accurately and use it cautiously. 

Others

Other types are represented by modified calcium lignosulfonate and modified tannin 

When a variety of water reducers are used together, attention should be paid to their mutual influence. In addition to the simple water-reducing performance, the compound water reducer can also have the characteristics of quick setting, early strength, anti-freezing, etc., according to the purpose of use. 

Superplasticizer Mechanism

In the process of cement mixing, flocculent particles are attracted to each other due to the existence of molecular attraction, and a flocculation structure is formed. Flocculation encapsulates part of the water used for mixing and reduces the workability of the concrete mixture.

The efficient water reducer has hydrophobic and hydrophilic characteristics, water reducer hydrophobic group directed adsorption on the surface of cement particles, hydrophilic group pointing to the aqueous solution and the formation of adsorption film.  Concrete mixing, due to the high-efficient water reducer, directional adsorption makes cement particle surface gay charge, the same, cement particles dispersed to each other, and condensation of flocculant of concrete structure collapse, water was released, supplement the moisture needed for the cement mixing, effectively increase the activity of the concrete mixture, to reduce the effect of the water. At the same time, the surface of cement particles due to efficient water reducer formed by the adsorption film between cement particles and particles contact more mellow, increasing the workability of concrete; The adsorption film also increases the surface area of cement particles and promotes hydration, which is conducive to improving the strength of concrete.

Cancer cells can "stretch out a big hand" and take away the mitochondria of immune cells. The Harvard Medical School research team cultured mouse and human breast cancer cells and immune cells, such as killer T cells, and used field emission scanning electron microscopy (FESEM) to observe the relationship between cancer cells and immune cells. interactive. Interestingly, they found that cancer cells stick out long nanotubes, typically within 100-1000 nanometers in diameter, each of which connects to multiple immune cells along the way. The researchers used the drug L-778123, which inhibits the formation of nanotubes, for treatment. The higher the concentration of L-778123, the better the treatment effect.

It is used in various high-tech fields, so the market demand for concrete water reducer will continue to rise. We are a quality supplier of concrete water reducer, please feel free to contact us.
