Alkali-free Concrete Additives Liquid Concrete Accelerator

Commodity prices are on track for their biggest rally in more than a century, while fixed-income assets have seen their longest run of outflows as the war in Ukraine adds to inflationary pressures in the global economy emerging from the coronavirus lockdown, according to Bank of America.

"Commodity prices this year are on track to record their biggest gains since 1915." the bank said in its weekly briefing. They cite many factors, such as pandemics, lockdown, civil strife, wars, excessive monetary and fiscal stimulus, and supply chain disruptions, that have led to "historically" high inflation.  

By the same token, it said government bonds were heading for their worst year since 1949, and "negative-yielding bonds will quietly disappear" from the market as central banks embark on a monetary tightening cycle and raise interest rates to tame soaring inflation.  

The prices of many commodities like the Concrete Additives are expected to increase in the future.

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.
