Global pce powder market trend 2024-2027 Effect of polycarboxylate superplasticizer by Newsibuonline

Oil futures tumbled more than $5 a barrel on news that the Biden administration is considering releasing about 1 million barrels a day from the U.S. Strategic Petroleum Reserve (SPR) for several months to cool surging crude prices.

Brent crude futures were down $4.71, or 4.2 percent, at $108.58 a barrel by 0035 GMT. U.S. West Texas Intermediate futures fell $5.45, or 5 percent, to $102.74 a barrel.

At an earlier time, gasoline prices had already reached record levels because of the Russia-Ukraine conflict.

The prices of other commodities like the pce powder are also expected to be volatile.

Polycarboxylate superplasticizer plays four main roles in concrete mixture: 1. In order to improve the pouring performance of concrete, the workability of concrete is improved without changing the composition of concrete. Under the given working conditions, the water-cement ratio of mixed water and concrete is reduced, and the strength and durability of concrete are improved. Under the condition of ensuring the pouring performance and strength of concrete, reduce the amount of water and cement, reduce creep, dry shrinkage, cement hydration heat and other factors that cause the initial defects of concrete; 4. The role of polycarboxylate superplasticizer in high grade can not be replaced by other admixtures.

Polycarboxylate superplasticizer Properties:

1. The amount of polycarboxylate superplasticizer is low, the water-reducing rate is high, the acid-based superplasticizer accounts for 0.80% of the cementitious materials, and the water-reducing rate can reach (20)%. When used in conjunction with fly ash, the water glue is relatively low and is suitable for the preparation of medium-and high-strength high-performance concrete.

2. The fluidity of concrete is large and the slump loss is small. Due to the good dispersion stability of polycarboxylate superplasticizer, the high fluidity concrete (slump ≥ 180mm) prepared by polycarboxylate superplasticizer has small time loss, no slump loss in one hour and less than 15% in two hours, which makes up for the defects of high slump loss and easy bleeding of concrete prepared with naphthalene superplasticizer. When combined with fly ash, excellent fluidity can be obtained with a small amount of superplasticizer, which can meet the technological requirements of producing commercial concrete, especially for pumping concrete.

3. Good adaptability to cementitious materials. In engineering practice, the cement produced by different manufacturers is mixed with a large amount of fly ash, and the polycarboxylate superplasticizer has good compatibility with different cements. there is no obvious bleeding segregation and hinders the growth of concrete strength, and because of its high water-reducing rate and adapting to the use of fly ash, the shrinkage of fly ash concrete is reduced and the pumpability of concrete is obviously improved. And the durability of concrete is improved. When the design strength grade of concrete is the same, the amount of cement increases, the amount of superplasticizer increases, the water-binder ratio decreases and the concrete strength increases; for different design strength grades of concrete, the amount of superplasticizer increases slightly with the increase of the amount of cementitious material, the water-binder ratio decreases, and the strength of concrete increases, but the concrete and workability remain stable as a whole, and the slump can reach (180 / 240) mm.

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.

According to a monthly monitoring report released by the Copernicus Climate change Service, an EU climate monitoring agency in Bologna, Italy, in July 2022, the Antarctic sea ice area was the lowest in 44 years of satellite monitoring records, 7% lower than the average.
