As the world deals with potential supply shortages, oil prices are soaring again, with more dramatic spikes and sudden drops expected.

For consumers, that means more expensive gas for longer - prices at the pump remain above $4 a gallon. For the economy, that means more inflation. In addition to the pressure on consumers, any business that relies on oil -- from airlines and truck drivers to chemical companies and plastics producers -- will face higher costs.

Mr Pickering estimates that 2m to 3m barrels a day of Russian oil shipped by water are frozen out of the market with no direct buyers. Due to the soaring oil price, the price of the polycarboxylate superplasticizer in the chemical industry will also be greatly affected. He said China and India are continuing to buy Russian crude. "I'm sure there will be others willing to take on more over time," he said. Mr Pickering said he did not expect oil to return to $130 a barrel, but added that it could happen. Francisco Branch, head of commodities and derivatives at Bank of America, said the US market was ready for cyclical price spikes and price swings in the polycarboxylate superplasticizer.

What is polycarboxylate superplasticizer?

Polycarboxylate superplasticizer is an important additive to ensure the strength of concrete and achieve pumping performance, and plays a pivotal role in improving and improving the operability of concrete construction. In this paper, according to the action mechanism and influencing factors of concrete water reducing agent in concrete construction, the optimal dosage of concrete water reducing agent is accurately determined, the dosage method of water reducing agent is found, and the compatibility and compatibility of water reducing agent with cement are verified. Adaptability, simply, accurately and reliably guarantee the quality of the project, reduce the cost of the project, and achieve the best effect of the construction project.

Why should polycarboxylate superplasticizer be added to concrete?

After the cement is mixed with water, many floc structures will be formed due to the gravitational effect between the cement particles, so that 10% to 30% of the water is wrapped in them, which greatly reduces the fluidity of the concrete mixture. When an appropriate amount of water-reducing agent is added, the molecules of the water-reducing agent are directionally adsorbed on the surface of the cement particles, and the hydrophilic group of the water-reducing agent points to the aqueous solution. And it increases with the increase of the concentration of the superplasticizer, resulting in electrostatic repulsion, which causes the cement particles to disperse each other, the flocculation structure disintegrates, the number of capillary pores is significantly reduced, and the mixing water wrapped in it is released, which can effectively increase the concrete mixing. fluidity and compactness.

After adding an appropriate amount of water-reducing agent to concrete, it can reduce the water-cement ratio of concrete, reduce the amount of cement, improve the early strength of concrete, advance concrete formwork removal time, accelerate formwork turnover, shorten construction period and reduce project cost.

There is a compatibility problem between superplasticizer and each component material of concrete, which has the greatest impact on cement, between the same cement and different superplasticizers, or between the same superplasticizer and different cements. There is a significant difference in the compatibility of concrete, and this difference will affect the rheological properties of concrete, thereby affecting the workability, strength and durability of concrete. Therefore, it is necessary to do a series of comparative tests for the selection of various types of concrete water reducers, as well as the performance and dosage of water reducers to determine the optimal dosage of concrete water reducers.

New Delhi: India is seeking to increase its purchases of crude oil from Brazil, the country's oil minister said recently after meeting his Brazilian counterpart.  

India is the world's third-largest importer and consumer of crude oil. Brazil currently supplies only a fraction of India's crude oil imports.  

India's state-owned companies Bharat Petroleum Corp and Oil and Natural Gas Corp have invested in oil and gas exploration in Brazil.  

India, which imports about 84% of its crude oil needs, is reducing its import bill by increasing biofuel use, among other things.  

India's state-owned fuel retailers are increasing ethanol storage capacity by 51 percent and the country plans to double the biofuel blend in petrol to 20 percent by 2025.  

India and Brazil are currently cooperating on biofuels and ethanol.

The prices of many commodities like the polycarboxylate superplasticizer are expected to increase in the future.
