The spread of the novel coronavirus is taking a direct hit on the operations of airlines in Asia. About 500,000 flights taking off and landing in mainland China have been canceled since January, according to aviation information company Cerium. Tourists and business trips have plummeted. On the booking website, there are a large number of air tickets for local routes with a price reduction of nearly 90% compared with the original price and only tens of yuan for a one-way trip.
In February, China's aviation industry recorded its largest single-month loss of 24.59 billion yuan, of which airlines lost 20.96 billion yuan.
Data from the Civil Aviation Administration of China showed that in February, the number of passengers traveling by air fell 84.5% year-on-year to 8.34 million.
The stagnation of the Asian aviation industry has brought volatility to concrete superplasticizer.
Introduction to Superplasticizer:
Superplasticizer, or high-efficient water reducing agent, has the functions of high efficient water reduction, slow coagulation, slump, and enhancement. It has strong adaptability to cement, less dosage, is easy to use, especially suitable for high-efficient water reduction and slow coagulation requirements of concrete engineering. The water reduction rate is 18% to 25%.
Differences between several kinds of Water Reducing Agent
It is a common water-reducing agent made of lignin. Most of its raw materials are extracted from coniferous trees and other species of material. This water reducing agent mixed with mortar can improve the fluidity of mortar, and enhance the solidification force of mortar. Its water reduction rate is about five to ten percent.
Naphthalene sulfonate water reducing agent:
It is a special water reducing agent. It is the product of naphthalene reacting with sulfuric acid and then fusing with formaldehyde. This water-reducing agent presents different colors from light to deep. It has strong water solubility and a good dispersion effect for a series of powdery building materials like cement. Its water reduction rate is about 10 percent higher than lignin.
Polycarboxylate-based high-performance water reducing agent:
It is a newly developed kind of reducing water agent using high technology. It is based on polycarboxylate as the main body of a variety of polymer organic compounds, graft copolymerization generated, with strong water reduction performance, is the world's leading technology environmental protection concrete admixture.
Its compatibility with all kinds of cement is good, the slump of concrete keeps the performance good, can prolong the construction time of concrete. It has a high water reduction rate with a low dosage. It can greatly improve the early and late strength of concrete. It has a low content of chloride ions and alkali, which is beneficial to the durability of concrete. It is a green environmental protection product with a pollution-free production process and without formaldehyde. It is suitable for precast and cast-in-place concrete, reinforced concrete, and prestressed concrete for high-speed railway, passenger dedicated lines, industrial and civil buildings, roads, bridges, ports and docks, airports, and other engineering construction. It is especially suitable for construction projects with long construction time and high requirements for concrete slumps, such as nuclear power projects.

Due to the impact of COVID-19, russia-Ukraine conflict and international trade friction, the global economy is facing great challenges. Overseas trade is shrinking, supply chains are not smooth, oil prices are rising, freight rates are rising, and global trade and economic recovery are becoming more uncertain, which brings many risks and challenges to the company's business. The price of the concrete superplasticizer can also be influenced by the above factors. To get the price of the latest concrete superplasticizer, you are welcome to send email contact.
