Global early strength agent market trend 2025-2026 What are Early Strength Agents? by Newsdfxt

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 early strength agent still face uncertainty.

What are Early Strength Agents?

Early strength agent is an admixture which accelerates the development of concrete early strength and has no significant effect on later strength. Early strength agent can accelerate the hardening process of concrete under normal temperature and low-temperature load temperature (not less than -5), and is used for winter construction and emergency repair projects.

 

Early Strength Agents Performance

Early strength agent refers to the admixture which can accelerate the development of early strength of concrete. The main mechanism of action is to accelerate the hydration rate of cement, and accelerate the early crystallization and precipitation of hydration products. The main function is to shorten the concrete construction curing period, speed up the construction progress, and improve the template turnover rate. 

 

Where can Early Strength Agents be Used? 

1. Early strength agent is suitable for steam curing concrete and normal temperature, low temperature and minimum temperature is not less than -5 environment construction of early strength requirements of concrete engineering. Early strength agent should not be used in hot environment. 

 

2.The chemical substances that harm the human body or pollute the environment after mixing concrete shall not be used as early strength agents. Early strength agent containing hexavalent chromium salt, nitrite, and other harmful components is strictly prohibited for drinking water engineering and food contact engineering. Ammonium nitrate shall not be used in office, residential and other construction projects.

 

Classification of Early Strength Agents 

Early strength agents mainly include inorganic salts (chlorine salts, phosphates) and organic amines, and organic-inorganic compounds.

 

1. Chloride salts early strength agents

Chlorine salts early strength agent mainly includes calcium chloride, potassium chloride, aluminum chloride and ferric chloride, among which calcium chloride is the most widely used. Calcium chloride is a white powdery substance, and its appropriate dosage is 0.5% ~ 1.0% of the cement quality, which can improve the 3d strength of concrete by 50% ~ 10% and the 7d strength by 20% ~ 40%. Meanwhile, it can reduce the freezing point of water in concrete and prevent concrete from being frozen in the early stage.

Using calcium chloride as early strength agent, the biggest disadvantage of containing Cl- ions, will make steel corrosion, and lead to concrete cracking. In order to inhibit the corrosion effect of calcium chloride on steel bars, calcium chloride and sodium nitrite (NaNO2) are often combined. 

 

2. Sulfate early strength agents

Sulfate early strength agent, mainly sodium sulfate, calcium thiosulfate, aluminum sulfate, aluminum potassium sulfate, and sodium sulfate is used more. Sodium sulfate is white powdery thing, the general admixture amount is 0.5% ~ 2.0%, when admixture amount is 1% ~ 1.5%, the time that achieves concrete design strength 70% can shorten half or so. 

Sodium sulfate has no corrosion effect on steel bar, and is suitable for concrete which is not allowed to be mixed with chlorine salt. However, due to its action with calcium hydroxide to generate strong alkali NaOH, in order to prevent alkali aggregate reaction, sodium sulfate is strictly prohibited for concrete containing active aggregate, at the same time, attention should be paid to not excessive mixing, so as not to lead to the late expansion of concrete cracking damage, and prevent concrete surface "frost". 

 

3. Organic amine early strength agents

Organic amine early strength agents mainly include triethanolamine, triisopropanolamine and so on, among which triethanolamine is the best early strength agent. 

Triethanolamine is a colorless or light-yellow oily liquid, alkaline, and soluble in water. The early strength of concrete can be improved by adding 0.02% ~ 0.05% of cement quality.  Triethanolamine has a slight retarding effect on concrete, and too much of it will cause serious retarding and concrete strength to drop, so the dosage should be strictly controlled.

China's non-manufacturing purchasing managers index for March was released by the China Federation of Logistics and Purchasing and the Service Industry Survey Center of the National Bureau of Statistics today. An index of business activity for the non-manufacturing sector as a whole fell below 50 percent. 

 China's non-manufacturing business activity index was 48.4%, down 3.2 percentage points from the previous month. The new orders index was 45.7 percent, down 1.9 percentage points from the previous month, indicating a significant slowdown in the growth of supply and demand in the non-manufacturing sector from the previous month.   In terms of sectors, the business activity index and new order index of transportation, accommodation and catering, culture, sports and entertainment, and tourism-related industries all declined significantly from the previous month. 

Then the early strength agent of the market may be affected by significant changes, the price will also be volatile, if you want to know the latest news of the early strength agent, welcome to contact us.
