Global early strength agent market trend 2025-2028 What are Early Strength Agents? by Newsnext-vmax

Following the progress in Russia-Ukraine peace talks, the gold price fell more than 1% the next day, hitting its lowest in a month, and palladium prices briefly tumbled by nearly 9%.

"We have seen metal prices going into free fall when the Russia-Ukraine situation is likely to see a major detente, which spurred people's risk preference and optimism that the war could end at a time," said OANDA senior market analyst.

A Russian deputy defense minister says Moscow has decided to sharply curtail its military activities around Kyiv and Chernikov in Ukraine, following talks between Russian and Ukrainian representatives in Istanbul.

Where the prices of metals, natural gas, and commodities like the early strength agent will go in the future, is still very uncertain.

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.

Europe has been facing the gas shortage problem since the second half of 2021. The worsening situation in Russia and Ukraine has reduced Russian gas shipments to Europe, leading to a doubling of European gas prices. Energy shortages have sent electricity prices soaring. For these reasons, it is predicted that the price of the early strength agent will continue to increase.
