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

U.S. natural gas futures rose about 5 percent to a near nine-week high as global energy prices surged on concerns over a pricing plan for energy exports, keeping U.S. LNG export demand near record highs. U.S. natural gas prices have risen despite forecasts of mild weather and lower-than-expected demand, which will allow utilities to fill up storage facilities next week. On Wednesday, Germany launched an emergency plan to manage gas supplies in Europe's largest economy. If natural gas supplies are interrupted or stopped, the German government could take unprecedented steps to limit electricity supply.
Affected by the increase in the price of natural gas, the price of the early strength agent will also increase.

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.

New Delhi: India's Oil Ministry recently conveyed its intention to five national oil companies including Indian Oil Corp and Bharat Petroleum Resources LTD to assess the possibility of buying shares in Russian oil projects sold by European and American oil majors.  

Bp announced it would give up its 19.75% stake in Rosneft, the Russian oil company.  ExxonMobil said on March 1 that it would exit about $4 billion in assets and terminate all of its Russian operations, including the Sakhalin-1 project in Russia's far East.  

India's oil ministry has asked the overseas investment arm of India's Oil and Gas Corporation to consider buying ExxonMobil's 30 percent stake in the Sakhalin 1 project in Russia's far East. ExxonMobil is the operator of the project and Indian companies already have a 20 percent stake in the project.

Because of the ever-changing international situation, the supply and prices of international bulk early strength agent are still very uncertain.
