Global superplasticizer for concrete admixture,superplasticizer used in concrete market trend 2023-2029 What does superplasticizer for concrete admixture do by Newsexpertcore.org

How serious are fertility problems today? People don't want to give birth,can't afford it, and can't give birth that has become the "three mountains".
The problem of childbirth is related to the people's livelihood. Whether a country can prosper or not depends on the population. I saw a set of data a few days ago. The data shows that on January 1, 1990, 2,784 babies were born in Shanghai. Ten years later, on January 1, 2000, 1,148 babies were born in Shanghai. In 2010, the number became 380. , 2020 only 156 people, the decline in the birth rate is shocking. The three most critical reasons are: I don't want to give birth, I can't afford it, I can't give birth! The decline of the global population will bring a series of economic and social problems, among which the demand for superplasticizer for concrete admixture,superplasticizer used in concrete will also be affected.


Superplasticizer used in concrete refers to the fact that after mixing, it can reduce the water demand of concrete under the condition of maintaining basically the same fluidity, thereby improving the strength and durability of concrete, or under the condition that the amount of cement used and the water-cement ratio remain unchanged , Add the admixture of concrete fluidity and improve concrete workability.


1. Lubrication effect: The polar hydrophilic groups in the concrete admixture superplasticizer are directionally adsorbed on the surface of the cement particles, and are easily associated with water molecules in the form of hydrogen bonds. The force of this hydrogen bond association effect far exceeds the molecular attraction between water molecules and cement particles. When the cement particles absorb sufficient water reducing agent, the surface layer of the cement particles forms a stable layer of solvated water by virtue of the association effect of R-SO3θ and the hydrogen bonds in the water molecules and the hydrogen bond association between the water molecules. The film plays a three-dimensional protective effect, blocks the direct contact between the cement particles, and plays a lubricating effect between the particles.

2. Wetting effect: After the cement is mixed with water, the surface layer of the particles is wetted by water, and its wet condition has a great influence on the characteristics of freshly mixed commercial concrete. amount that can be reduced.

3. Water reduction effect:After adding a superplasticizer to the commercial concrete, the water-cement ratio can be significantly reduced under the condition of maintaining fluidity. The water reducing rate of high-efficiency water-reducing agent can reach 10% to 25%, while the water-reducing rate of ordinary water-reducing agent is 5%-15%, and high-efficiency water-reducing agent is also famous for this. The reason for the water reducing effect is mainly because of the adsorption and dispersion effect of commercial concrete on the water reducing agent.

4. Plasticizing effect:After adding the polycarboxylate based superplasticizer to the commercial concrete, the fluidity can be added without changing the water-cement ratio. The usual water-reducing agent can increase the slump of freshly mixed commercial concrete by more than 10 cm under the condition that the amount of cement used remains unchanged.

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 superplasticizer for concrete admixture,superplasticizer used in concrete may continue to rise in the future.
