Global concrete water reducer market trend 2022-2029 Types of High-efficient Water Reducer by Newsjeromechampagne2015

After Russia pledged to scale back its military operations around Kyiv and in northern Ukraine, the prices of most industrial metals fell, led by aluminum, showing people's concerns for supply shortage eased.

At an earlier time, the West imposed sweeping sanctions on Russia for its invasion of Ukraine, which aroused concerns about the supply problem because Russia is a major producer of nickel, aluminum, and copper. 

Russia is also a major gas supplier to Europe, where potential supply disruptions are seen as hitting power-intensive aluminum and zinc 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.

Inflationary pressures on Canadians continue to rise. The consumer-price index rose 6.7% in March from a year earlier, the biggest increase since January 1991, according to the latest figures from Statistics Canada.  

On a month-on-month basis, Canada's CPI rose 1.4 percent in March, also accelerating from February's 1.0 percent rise.  

Prices in the eight major sectors covered by the statistics continued to rise. The uptrend comes against the backdrop of continued price pressures in the Canadian housing market, widespread supply chain constraints, and geopolitical conflicts, according to CBC. A variety of factors have affected energy, commodity, and agricultural markets. Meanwhile, Canada's employment picture continued to improve in March, with the unemployment rate falling to a record low and the average hourly earnings of employees rising.  

Excluding gasoline, Canada's CPI rose 5.5 percent year on year in March.  It is also the highest since comparable data began in 1999.  

The widespread supply chain constraints and geopolitical conflicts are expected to continue to affect the prices of the concrete water reducer.
