Product Description
Sodium acetate is also known as sodium acetate trihydrate, sodium acetate, chemical formula C2H3NaO2·3H2O. It is a common inorganic compound, with a transparent crystal, easily soluble in water, insoluble in organic solvents such as ethanol. Sodium acetate has a PH value of 7.5-9.0 and is white or slightly yellow at room temperature. It is a non-toxic and harmless chemical substance.
The crystal water is lost at 123℃. Usually wet, it has an acetic acid taste. Hydrolysis occurs in water.
Application
Concrete Hardening Accelerating / Concrete early strength agent
Concrete early strength agent refers to the admixture that can improve the early strength of concrete, which is mostly used in winter or emergency repair. The early strength agent has no significant effect on the later strength of concrete.
Sodium acetate concrete accelerator has been widely used in concrete engineering. Its main function is to accelerate the hardening time of concrete while improving the strength of concrete, which has the following advantages:
1. Promote the hardening process of concrete, shorten the curing time of concrete, and improve construction efficiency.
2. Accelerate cement hydration reaction, and improve concrete strength and durability.
3. Shorten the early strength period of concrete, improve the strength of concrete, and improve the workability of concrete.
4. Reduce the shrinkage of concrete, reduce the risk of cracking of concrete, and improve the durability of concrete
Dosage and precautions
When adding sodium acetate to concrete, the amount should be determined according to the actual situation such as the type of concrete material and ambient temperature. Generally speaking, the best addition of sodium acetate is 0.5% to 2% of the cement content. At the same time, the following matters need to be noted when using sodium acetate:
1. Sodium acetate should be mixed with water and then mixed with concrete.
2. In the construction process of concrete using sodium acetate, it is necessary to carry out construction by the construction specifications of the cement mixture.
3. In the use of sodium acetate concrete should avoid adding other chemical reagents.
4. The package of sodium acetate should be sealed and stored in a dry and ventilated place.
