Guotai Junan released a research report saying that under the background of carbon neutrality, the scarcity of coal mines is prominent, and the value of assets will continue to increase. The high point of capital expenditure in the coal industry appeared in 2012. Under the general direction of carbon neutrality, the overall investment in the industry has slowed down, and capital expenditure has gradually declined. From 2021 to now, the Energy Bureau of the National Development and Reform Commission has only newly approved 17.4 million tons of production capacity. In the context of scientific carbon reduction, coal consumption will continue to dominate for a long time, and the scarcity of new batches of production capacity will drive up asset prices. The core increase in demand is provided by traditional energy sources, driving oil and natural gas prices to continue to rise, and overseas coal prices hitting new highs. The rise in coal prices will also drive up the price of Concrete Additives.

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.

According to "Science and Technology Daily", a research report provided by Ai Jun and others from the Fourth Hospital of Hebei Medical University showed that seven anticancer drugs including cisplatin had obvious inhibitory effects on gastric cancer cells (BGC-823) in vitro. However, there are certain differences, and it is ideal to use a medium concentration for 48 hours.
