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 crack reducing admixture.
Description of concrete crack reducing admixture
Cement anti-crack agent is Tongrun's full use of the physical and chemical changes in the cement curing process. The chemically synthesized powder can prevent cracking and cracking from both physical and chemical aspects, which can significantly improve the strength of lightweight concrete.
The anti-cracking agent can effectively solve the problem of the natural cracking of cement products. Adding the anti-cracking agent to lightweight concrete can reduce the cracks and hollowing of lightweight concrete, increase the strength of mortar and improve the quality of the project.
The anti-crack agent solves the problems of large shrinkage deformation, poor impermeability, and weak crack resistance of ordinary cement products. Directly incorporated into cement can effectively control the plastic shrinkage and cracks caused by segregation of lightweight concrete, significantly improving the strength of lightweight concrete cracking performance, anti-freezing, and anti-shock performance and wear resistance and earthquake resistance.
Usage of concrete crack reducing admixture
Concrete crack reducing admixture can be used to solve the crack problem of bridges, highways, runways, dams, cement products, mortar.
Especially suitable for various products of lightweight concrete.
Characteristic of concrete crack reducing admixture
(1) Crack resistance: The crack resistance agent is easily dispersed in lightweight concrete to form a three-dimensional space structure, which effectively improves the phenomenon of reduced hardening and cracking caused by too fast drying of mortar and insufficient moisture;
(2) Low shrinkage: the mixture will not shrink and settle, and the anti-crack agent can absorb internal stress and improve crack resistance;
(3)Operability: Anti-crack agent can increase the plasticity of mortar, improve construction operability and work efficiency;
(4) Anti-slip property: Because the anti-crack agent has a thickening effect, it can prevent or avoid the slippage of mortar and adherend during construction to a certain extent.
Instructions of concrete crack reducing admixture
The recommended dosage is 1.5-3kg/m3, and the precise usage needs to be determined after debugging;
When using it, it is best to dissolve the anti-crack agent in the required water, and then add it to the mixer to stir, and then it can be used.
Storage and transportation of cement anti-crack agent
(1)The anti-crack agent packaging specification is 20 kg/bag, non-toxic and non-flammable, and can be transported as general cargo;
(2)The anti-crack agent should be stored in a cool and dry place to avoid rain and moisture, and the shelf life is 24 months.

Recently, the first press conference of the Boao Forum For Asia Annual Conference 2022 was held. Two flagship reports were released at the conference: "Asia's Economic Prospects and Integration Process 2022" and "Sustainable Asia and the World 2022-Green Transformation in Action in Asia".
The flagship report points out that the global economy will recover in 2021, and the pace of economic integration in the Asia-Pacific has not stopped even in the face of the impact of COVID-19. The Asia-Pacific region has provided new impetus for the world's economic recovery and institutional building.
The report gives an outlook on the Asian economy, noting that a number of factors will affect Asian economic growth. For example, mutated strains such as Delta and Omicron have become more transmissible, and many economies are experiencing epidemic peaks again. The Ukraine crisis has triggered geopolitical changes in Asia and Europe, leading to higher commodity prices, which may affect the global energy supply and energy transformation.
The report pointed out that the Asian economy will still be in the process of recovery in 2022, but the growth rate may moderate. According to the report, Asia's economic growth in 2022 is likely to be lower than the current IMF forecast, which is projected at 4.8%.
Affected by several factors, the supply of the Concrete crack reducing admixture is erratic and thus its prices are expected to go higher in the future.
