Global Concrete strength and shrinkage reducer market trend 2022-2030 Concrete strength and shrinkage reducer by Newsdesignerstudiostore

A wave of layoffs that has swept the entire Internet industry has intensified. China's Internet industry has experienced several crises and major changes in the past development process. There is also a "brief history of layoffs by major Internet companies". Hot search, JD.com has a wide range of layoffs in this round of layoffs, and all its subsidiaries are involved. Most of the layoffs are between 10% and 20%. Among them, Jingxi Guangdong and other theaters have all laid off staff. Tencent also reported the news of downsizing and layoffs. Among them, Tencent PCG (Platform User Content Business Group) laid off 30% of its staff, iQiyi laid off 12% of its staff, Kuaishou was reported to have laid off 30% of its staff, and the e-sports department of Station B laid off 90% of its staff.
Mass layoffs on the internet have created a host of socioeconomic issues, including Concrete strength and shrinkage reducer.

Description of Concrete strength and shrinkage reducer

1. After adding concrete strength shrinkage enhancer to carbonate cement, it can effectively improve the early and late strength (strength is increased by 5-30%), improve the mold turnover rate, and can also reduce the steam curing temperature or shorten the steam curing time.

2. The coagulant strength-promoting and shrinkage-reducing agent gives the micro-expansion performance to compensate for dry shrinkage, reduce the mixing shrinkage, and improve the crack resistance.

3. Adding a strength-promoting shrink-reducing agent can greatly reduce the amount of Portland cement and reduce the cost of concrete when the early strong friction is not pursued.

4. The dosage of Portland cement can be appropriately reduced after adding concrete strength-enhancing and shrinkage-reducing agent, and low cement and low glue material can still be prepared to reduce the hydration heat release of high-grade and large-volume concrete, and reduce the temperature difference between the center temperature and the surface temperature of the concrete. Reduce the risk of cracking in mass concrete.

5. The strength, impermeability, freeze-thaw resistance, carbonization resistance, and volumetric properties of concrete mixed with strength-promoting shrinkage-reducing agent have been significantly improved.

The mechanism of Concrete strength and shrinkage reducer

1. With the addition of strength-promoting and shrinkage-reducing agent, calcium sulfoaluminate minerals, calcium sulfate calcined at a higher temperature, high-activity calcium oxide, and Portland cement are compounded and reacted with water to make the calcium aluminate in Portland cement. The aluminum oxide and calcium oxide in the mixed materials such as minerals and slag react to form ettringite hydrated minerals with fast hardness, high strength and slight swelling, so that the potential activity of the mixed materials such as slag can be fully developed. , thereby improving the early and late strength of concrete.

2. The expansive hydration products such as mayvandite and calcium sulfate in the composite system and the organic and inorganic strength-shrinking-promoting components in the strength-promoting and shrinking-reducing agent have the expansion function to compensate for dry shrinkage and improve the crack resistance of concrete. Densification performance and frost resistance, etc.

3. In the composite system concrete, the cohesion is increased due to physical and chemical effects, and segregation and bleeding are avoided.

4. The alkali-free chemical activator accelerates and improves the degree of hydration of cement minerals, thereby improving the early and early strength of concrete.

5. Expansive hydrates such as ettringite and calcium sulfate in the composite system and the shrinkage-reducing components in the strength-promoting shrinkage-reducing agent improve the crack resistance, compactness, frost resistance and impermeability of the mixed soil.

The negative electrode material is the carrier of lithium ions and electrons during the charging process of the battery and plays the role of energy storage and release. In the battery cost, the negative electrode material accounts for about 5%-15%, which is one of the important raw materials for lithium-ion batteries. The global sales of lithium battery anode materials are about 100,000 tons, mainly in China and Japan. According to the current growth trend of new energy vehicles, the demand for anode materials will also show a state of continuous growth. At present, the global lithium battery anode materials are still dominated by natural/artificial graphite, and new anode materials such as mesh carbon microspheres (MCMB), lithium titanate, silicon-based anodes, HC/SC, and metal lithium are also growing rapidly.
Our company provides anode materials and Concrete strength and shrinkage reducer. If you need to know more anode materials and Concrete strength and shrinkage reducer, please feel free to contact us.
