Global early strength agent market trend 2022-2026 Differences between Early Strength Agents and Accelerating Agents by Newsrobocup2009.org

Koalas were declared endangered in eastern Australia on Friday, with more and more koalas dying from disease, habitat loss, and other threats. Earlier, the koala was considered a vulnerable species, and the Commonwealth Department of the Environment changed its protection level to endangered on the east coast of Queensland, New South Wales, and the Australian Capital Territory. Many koalas in Australia are infected with chlamydia. The disease can cause blindness, infection, and infertility. Last year, the Australian Koala Foundation said Australia had lost about 30 percent of its koala population in the past three years. Without immediate action, the species could become extinct by 2050.
Unlike koalas, which are on the brink of extinction, the market demand for early strength agent will grow substantially.

Definition:

Accelerating agent is to point to the admixture that can make concrete condenses quickly after concrete hardening. 

Early strength agent refers to the admixture which can improve the early strength of concrete and has no significant effect on the late strength. 

 

Classification:

The main types of accelerating agent:

alkali earth metal carbonate and alkali earth metal hydroxide, silicate alkali (sodium silicate) sodium silicate, potassium silicate accelerating agent, sodium aluminate, potassium aluminate accelerating agent, alkali free liquid accelerating agent. 

Early strength agents can be divided into:

strong electrolyte inorganic salts, water-soluble organic compounds, organic and inorganic compound early strength agents according to their chemical composition. 

 

Main ingredients 

The main ingredient of accelerating agent is aluminum oxide clinker (namely bauxite, soda, quicklime according to the proportion of the clinker fired) by grinding and made. 

Early strength agent in addition to chlorine salt and sulfate nitrite, chromate and other organic compounds such as triethanolamine, calcium formate, urea and so on. 

 

Uses

Accelerating agent dosage accounts for only 4% ~ 6% of cement dosage in concrete, but can make concrete in 5min initial coagulation, 10min final coagulation. In order to achieve the purpose of rush repair or fast condensation of concrete in the tunnel. It is an indispensable additive in shotcrete construction method. Their function is to speed up the hydration and hardening of cement, forming sufficient strength in a very short period of time to ensure the requirements of special construction. 

 

Early strength agent does not contain chloride ion, no corrosion of steel bar, applicable to all civil and industrial buildings and prestressed reinforced concrete members, mortar and so on. It is most suitable for construction under low temperature in early winter and early spring. Used in Portland cement, slag cement is particularly significant in strengthening and modifying. 

 

Note:

Accelerating agent should not be added while material is mixed, because stones, sand contains a lot of water, accelerating agent in a short time of water absorption in the non-spraying decomposition of its rapid setting components, affecting the setting time, reducing the strength of concrete, it will lead to the adverse effect of spraying concrete. Before use, the cement used in the project should be tested, and the dosage can be used in large quantities. 

 

Early strength agent dosage is 3-6% of cement. In order to keep the quality of concrete mixed with this agent uniform, mixing time to extend 1-2 minutes. Concrete mixed with early strength agent cannot use orthopedic active minerals (such as opal). If problems such as damp agglomerate arise, the agent must be crushed or weathered, and its performance will be unchanged.

According to Reuters, U.S. Treasury officials said they would discuss with G7 leaders pricing caps and tariffs on Russian oil as an alternative to the embargo, which would keep the market supplied, limit price spikes, and reduce Russian revenues.  

The EU foreign ministers' meeting was held in Brussels.  The meeting failed to agree on the sixth round of sanctions, including an oil embargo on Russia, because of objections from Hungary.  

EU High Representative for Foreign Affairs and Security Policy said at a press conference after the meeting, that the meeting failed to reach an agreement on the final adoption of the sixth round of sanctions, the permanent representatives of member states to the EU will continue to discuss. The foreign ministers faced similar difficulties trying to reach an agreement on an oil ban. He said Hungary's position was based on economic rather than political concerns.  

Hungary is highly dependent on Russia for energy, getting more than 60 percent of its oil and 85 percent of its natural gas from Russia.  

A few days ago, the European Commission submitted the sixth round of proposed sanctions against Russia, including a total ban on Russian oil imports by the end of this year. Hungary immediately objected and said it wanted substantial compensation from the EU to offset its loss from giving up Russian oil.

The early strength agent price is predicted to increase in the next few days, due to geopolitical factors.
