Global water reducer,polycarboxylic acid superplasticizer market trend 2024-2030 Characteristics and types of high performance water reducer by Newsapelslice

Roche and its subsidiary TIB Molbiol have developed a series of tests for the detection of the monkeypox virus, the Switzerland-based pharmaceutical company announced.  

The monkeypox virus is a close relative of the smallpox virus, belonging to orthpoxviridae in the poxviridae family.  

The modular virus detection tool, called LightMix, includes three orthpoxvirus detection kits with different functions, Roche said in a statement. The first kit detects orthpoxvirus; The second kit tests only for monkeypox virus (west and Central African branches); The third kit contains the main functions of the first two kits, showing specific information on the presence of the monkeypox virus (west and Central African branches) as well as the detection of orpoxvirus.

Thomas Schinek, a Roche executive, said the new test could detect monkeypox and help track its spread. Such diagnostic tools are critical for addressing and ultimately managing emerging public health challenges, as they advance responses such as tracking efforts and treatment strategies.  

The monkeypox virus was first identified in 1958 in a group of monkeys used for research when the animals developed a "pox-like" infection, hence the name. Since May, several non-endemic countries have reported human cases of the monkeypox virus, including the United Kingdom, the United States, Portugal, Spain, and Italy.

Affected by the ever-changing international situation, the supply and prices of international bulk water reducer,polycarboxylic acid superplasticizer are still very uncertain.


What is polycarboxylic acid superplasticizer?

As an admixture, concrete superplasticizer is added to concrete to reduce water consumption and increase the strength of concrete. At present, the high-performance water-reducing agents used in concrete engineering are mainly polycarboxylic acid superplasticizer products.


1. Features of high performance water reducing agent concrete

(1) High water reduction rate. Under the same slump, the water reducing rate of high-performance water reducing agent is relatively high, and its water reducing rate is generally above 35%. Due to the high water-reducing rate of the water-reducing agent, the water consumption of concrete is greatly reduced. When calculating the parameters of the water reducing agent, it should be calculated according to 0.25% of the cement amount, and high-performance concrete can be prepared by increasing the amount of admixtures.

(2) Good liquidity. Generally speaking, in the application process of high-performance water reducer, the flow performance will not deteriorate, which is beneficial to reduce the occurrence of concrete segregation or tube pump blockage. To ensure the performance of the concrete mixture, the water reducing agent should be selected according to the variety of cement to ensure the quality of the construction project.

(3) The strength of the mixture is improved. Adding water reducing agents (such as slag, fly ash, etc.) to concrete can improve the strength of the mixture. In the case of ensuring the stability of the cement dosage, adding a high-performance water reducer to the concrete can increase the strength of the concrete to more than 70%.

(4) The total alkali content is low. Adding an appropriate amount of high-performance water reducer to concrete will reduce the alkali content of concrete, reduce the incidence of alkali-aggregate reaction to a certain extent, and improve the durability of concrete.

(5) The shrinkage is lower. Since the performance of polycarboxylate water reducer is relatively good, it can ensure the quality of formula raw materials in the selection of raw materials. In addition, the total alkali content of the water reducing agent is low, which is conducive to maintaining the stability of the concrete and preventing the occurrence of concrete cracks.


2. Types of high performance superplasticizers

High-performance water reducers are mainly divided into three types: slump-preserving type, functional type and shrinkage-reducing type. These types are briefly described below.

(1) Collapse protection type. The slump-preserving water-reducing agent is generally used in the development of concrete. By adding this type of water-reducing agent, the slump of concrete can be ensured and the fluidity of concrete can be reasonably controlled.

(2) Functional type. The functional type of water reducing agent is mainly divided into two functions, one is early strength type and the other is retarded type. Among them, the early-strength water-reducing agent can make the concrete meet the exothermic requirements in the early stage and promote the coagulation of the concrete, which is beneficial to the construction of the concrete in winter. However, the application of retarder water reducing agent in concrete mainly reflects the ability to maintain the concrete state, so as to facilitate the repair of concrete in the later stage. However, if these two water reducers are used in combination, they can play a role in retarding the setting of cement.

(3) Reduced type. The shrinkage-reducing type of the water-reducing agent is mainly synthesized by esterification, which not only has a certain water-reducing effect and shrinkage-reducing function, but also fully exerts the water-reducing effect of concrete.

The war in Russia and Ukraine is roiling global financial markets. Russia and Ukraine are important commodity suppliers in the world, so their conflict is bound to make a full impact on the global commodity supply. In view of this, the price of the water reducer,polycarboxylic acid superplasticizer may continue to rise in the future.
