Under the spread of the new crown epidemic, after Americans experienced life and death, they set off the largest "resignation wave" in history, and the number of resignations broke the highest record since statistics began in 2000. Since April this year, more than 4 million people in the United States have voluntarily resigned each month. In August, the number of resignations exceeded 4.27 million, and in November, it rose to 4.4 million. The operation of society is linked. The large number of departures in the United States has led to a large shortage of labor; and the shortage of a large number of labor has directly led to the supply chain crisis in the United States; the supply chain crisis has directly affected prices and prices in the United States. The economy has a direct effect on people's lives.
The economic downturn will affect the market demand for concrete additive.
At first, concrete additives were used only to save cement. With the development of construction technology, admixture has become the main measure to improve the performance of concrete.
What are advantages of concrete additives?
It can reduce the water consumption of concrete. Or the fluidity of concrete can be increased without increasing water consumption.
The setting time of concrete can be adjusted.
Reduce bleeding and segregation. Improve workability and water elutriation resistance.
The slump loss can be reduced. Increase the pumpability of pumping concrete.
It can reduce contraction. The addition of expansive agent can also compensate for shrinkage.
Delay the initial hydration heat of concrete. Reduce the temperature rise rate of mass concrete and reduce the occurrence of cracks.
Improve the early strength of concrete. Prevent freezing at negative temperature.
Improve strength, increase frost resistance, impermeability, wear resistance, corrosion resistance.
Control alkali-aggregate reaction. Prevent the corrosion of steel bar and reduce the diffusion of chloride ion.
Made into concrete with other special properties.
Reduce the viscosity coefficient of concrete.
Where are concrete admixtures used?
1. It is suitable for mass concrete, high-strength and high-performance concrete, roller compacted concrete, concrete constructed in hot weather, concrete poured in a large area, concrete produced by cold joints, concrete that needs to be parked or transported for a long time, self-leveling vibration-free concrete, slip form construction or horizontal construction and other concrete that needs to delay setting time.
2. It is suitable for different grades of concrete under the daily minimum temperature of 5 degrees Celsius, as well as various continuous pouring projects of high flow concrete, commercial concrete, pumping concrete, prestress and reinforced concrete.
3. It is not suitable to be used alone for concrete with early strength requirements and steam curing concrete.

Ukrainian media recently reported that Ukraine will build a food transfer station in the Chernovze region, and the first phase is scheduled to be completed by the end of 2022. According to reports, the completion of the project will help ease the current congestion in grain shipments, and it is estimated that the transfer station will be able to handle 3 million tons of grain per year and store up to 200000 tons of grain at the same time.
According to the Cuban Electric Union on August 8, affected by the fire at the oil reserve base in Matansas province, the Antonio Guiteras thermal power plant near the oil storage base stopped operation at about 13:00 local time. It is reported that the shutdown of the thermal power plant is due to water shortage, and although measures have been taken to supply water to the plant through pipelines, it is still not enough to maintain its operation. The Cuban electricity Union said it could not guarantee that the thermal power plant would resume operation during peak hours.
