Types of High-efficient Water Reducer

If you are looking for high-quality products, please feel free to contact us and send an inquiry, email: brad@ihpa.net



The purchasing pace at the demand end of the international thermal coal market continues to slow down and the international thermal coal price continues to decline. Prices for thermal coal at major international ports continued to fall last week as buyers in Europe slowed in recent days for April, coupled with weaker-than-expected import demand from End users in China. According to China Coal Market net monitoring:  Australia Newcastle port thermal coal price index was 253 USD/ton, compared with 309.02 USD/ton, down 56.02 USD/ton, down 18.13%. South Africa's Port Richards thermal coal price Index was $264.5 / mt, down the US $62.72 / mt or 19.17% from US $327.22 / mt. The European ARA Tri-port thermal coal price Index was $281.8 / ton. Does the price of thermal coal in major international ports continue to decline to affect the price of the concrete water reducer? 

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.
