Alkali-free Concrete Additives Liquid Concrete Accelerator

Risk aversion plunged on the positive news of the Russia-Ukraine talks. After several days of rising oil prices, the price of precious metals continued to fall. Domestic futures markets remain stable for the time being.

Back in international markets, WTI crude futures briefly dipped below $100 a barrel, while Brent crude hit its lowest intraday level in nearly two weeks. Spot gold briefly fell below $1,900 an ounce. Comex gold futures closed down 1.1 percent at $1,918.4 an ounce. Comex silver futures closed down 1.14 percent at $24.91 an ounce. "Recently, crude oil prices have been extremely sensitive to changes in geopolitical news." Traders believe that the current oil price is still in the broad impact, Ukraine will still be a premium in the case, although the market further decline, but should not be too pessimistic, it is recommended to wait and see for the time being. The Ukrainian premium is still there and there will be some volatility in the Concrete Additives market.

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.

Gas supplies have been in short supply because of the conflict between Russia and Ukraine.  Combined with the situation that other renewable sources cannot produce enough electricity, electricity prices have soared in many parts all over the world. For this reason, I assume the supply and prices of the Concrete Additives would keep being influenced by the high energy prices.
