Analysts at JPMorgan recommended selling or "underweight" emerging market local currency sovereign debt because of the global impact of the Ukraine-Russia crisis.

JPMorgan estimated that fixed-income assets in emerging markets have lost 6-9 percent of their value since Russia invaded Ukraine a month ago, with nervousness about the war and its impact on global energy and food prices adding to existing pressures.

Some leading emerging market central banks are signaling that interest rates now need to rise faster than previously expected, which fuels fears of "stagflation". Stagflation means when high inflation and higher interest rates undermine economic growth.  

With both the U.S. Federal Reserve and emerging market central banks raising interest rates, JPMorgan also said it made sense to "underweight" emerging market assets by taking advantage of the recent pullback in local currency bond yields relative to TREASURIES.  

JPMorgan said major metals exporters such as South Africa, Chile, and Peru could still do well, but warned that emerging market fixed income assets now faced a more "stagflationary" trajectory.

The markets and prices of many commodities, metals, chemicals like the Concrete Additives still face uncertainty.

1. Introduction of Alkali-free concrete accelerator

Alkali-free concrete accelerator is a new generation, environmentally-friendly, chlorine-free and alkali-free liquid accelerator developed by using a new synthetic technology of inorganic and organic materials. It can significantly promote water and mud hydration and increase the strength of concrete, and it has good compatibility with various cements.

The alkali-free concrete accelerator can be widely used in the wet spraying construction process of various projects, reducing dust during construction, less rebound loss, good concrete homogeneity, and significant economic benefits.

2. Technical performance of Alkali-free concrete accelerator

The setting time is fast, the initial setting adhesion is good, and the thickness of one shot can be 8-150mm. Low resilience and good workability. The working face is free of dust, chlorine, and alkali, which is beneficial to the health of operators. There is basically no loss in the later strength of concrete.

3. Dosage range of Alkali-free concrete accelerator

The dosage of this agent is 6-9% of the cement weight. It can replace the same amount of water, and the actual mixing amount should be determined after adjustments are made according to the cement type, label and construction temperature.

4. Scope of adaptation of Alkali-free concrete accelerator

This product is suitable for spray concrete construction and leak plugging of underground engineering such as mine engineering, coal mine, shaft engineering, highway, railway, traffic tunnel engineering, shotcrete anchor support concrete, urban construction, national defense, water conservancy, and ground cement concrete. Construction and concrete emergency rescue, emergency repair and reinforcement works.

5. How to use Alkali-free concrete accelerator

Before using this agent, it is necessary to make a trial mix of the cement and this agent for adaptability and optimum mixing amount. It is recommended to use a water reducing agent in conjunction with a low water-cement ratio to achieve better results.

The content of accelerator can be controlled by a flow hopper or a precision water meter.

This product should be stirred evenly after opening the barrel. If it cannot be used up at one time, it should be sealed and stored.

If it comes in contact with the skin, rinse immediately with clean water, if it splashes into the eyes, rinse with clean water, and seek medical help for disposal.

6. Packaging and storage of Alkali-free concrete accelerator

Packed in plastic drum, 250kg/drum, can be packed according to user requirements.

During transportation, load and unload with care to prevent spillage. It should be stored in a warehouse, protected from rain and sun. The validity period is six months.

There is basically no loss in the later strength of concrete. Researchers at the Centre for Translational Atomic Materials at Swinburne University of Technology, Melbourne, Australia have developed a new graphene film that absorbs more than 90% of sunlight while eliminating most of the infrared thermal emission losses, a highly efficient A solar-heated metamaterial capable of rapidly heating to 83 degrees Celsius (181 degrees Fahrenheit) in an open environment with minimal heat loss. Proposed applications for the film include thermal energy harvesting and storage, solar thermal power generation, and seawater desalination.
