Prices in the national electricity market averaged $87 per megawatt-hour in the first three months of the year, above the level promised by the federal government. Wholesale electricity prices for industry and large businesses have already exceeded the level promised by the federal government, adding another cost pressure to the economy. Prices in the national electricity market averaged $87 per megawatt-hour in the first three months of this year, up more than two-thirds from the December 2021 quarter, the Australian Energy Market Operator (AEMO) said recently. That's up 141% from the March 2021 quarter.
Because of the ever-changing international situation, the supply and prices of international bulk pce powder are still very uncertain.
Polycarboxylate superplasticizer is based on unsaturated polymerizable monomers with active groups such as carboxyl group, sulfonic acid group, hydroxyl group and polyoxene group as raw materials. some new high-performance dispersants are prepared by direct copolymerization, post-polymerization functionalization or in-situ polymerization and grafting, which are called superplasticizers in concrete.
The unique comb-shaped molecular structure of this kind of superplasticizer gives it the characteristics of low content, high water reduction, good water retention and good strengthening effect. In addition, the molecular structure, molecular weight and its distribution can be adjusted by means of flexibility of molecular structure design and control of synthesis process parameters, so as to achieve high performance.
What are the advantages of polycarboxylate superplasticizer?
1. low content and good dispersion, usually in the amount of 0.2%-0.5% of the amount of cementitious material, the water reduction rate of concrete can reach more than 30%, and does not segregate and does not bleed water.
2. The performance of keeping slump is good, and the slump of concrete in 90~120min is basically no loss, which accords with the development trend of modern pumping concrete.
3. It has good compatibility with cement, admixture and other admixtures, so it can be used freely.
4. It can effectively increase the content of fly ash, ground slag and other admixtures used to replace cement, so as to reduce the cost of concrete.
5. It can be used to prepare ordinary, high strength, ultra-high strength, high fluidity, early strength, mass concrete and so on according to different design requirements.
6. Formaldehyde is not used in the preparation process, so it will not cause pollution to the human body and the environment.

With Russia taking the lead on Poland and Bulgaria at the end of last month, there appears to be a growing sense of compromise within the EU over whether to accept Moscow's proposed rouble settlement order.
Italy's prime minister said recently that European companies would be able to buy gas in roubles without violating sanctions. This apparently ignores the guidance of hardliners in the EU to "fight to the end".
For weeks, European companies have been trying to find ways to meet Russia's payment demands for the rouble while maintaining vital gas supplies without violating sanctions against Moscow.
Late last month, European Commission President Von der Leyen said operating under the mechanism would violate sanctions and asked European companies not to bow to Russian demands. However, the EU has yet to issue more rigorous written guidelines on how companies should pay Gazprom.
The Italian prime minister said recently, "There is no official announcement from the European Union about what ruble settlement means for sanctions violations, and no one has said whether ruble payments violate sanctions or not. It's a grey area."
"In fact, most gas importers are already opening rouble accounts for deals with Gazprom,"
He also used German companies as a shield. He said Germany's largest gas importer had already paid in rubles. "In fact, we saw evidence yesterday that the largest gas importer in Germany has already paid in rubles."
