Uses

1. PC-AE can be used as air-entraining agent for concrete, mortar and the other products, especially for wet concrete environment of hard water and an alkaline environment (high calcium ions and high PH value).

2.Compared to the other air-entraining agents, PC-AE’s efficiency is higher and its lower amount could achieve the same air-entraining effect. PC-AE also has a specific application, such as the foaming agent of floor tile.

3.PC-AE can produce a large number of uniform microbubbles in concrete admixtures, whose foam particle size is below 300 microns in dry concrete. The air content is up to 5%.

Dosage

PC-AE’s dosage is 0.01-0.1% of water-reducing agent’s weight.

Storage

> 30℃ storage will cause the surface gel. After stirring, the gel will be eliminated and may be used again. If the product is in <20℃ environment, there may be precipitation in effective material. You can re-heat and stir this product to be mixed unevenly. However, the heating temperature is not higher than 50 ℃.

Shelf Life

At room temperature, PC-AE can be stable for one year without opening the storage. The prolonged storage will lead to the lower PH value.

Giant concrete admixtures are in the form of chemical admixtures, precast admixtures and construction chemical, admixtures used by ready-mix concrete plants, precast admixtures used by the concrete plant and concrete additives which reduce usage of water, improve durability and workability of concrete, and increase compression strength of concrete.

Concrete Admixtures and Concrete Additive Types as Follows:

Type A—Water-reducing admixtures & additive,

Type B—Retarding admixtures & additive,

Type C—Accelerating admixtures & additive,

Type D—Water-reducing and retarding admixtures & additive,

Type E—Water-reducing and accelerating admixtures & additive,

Type F—Water-reducing, high range admixtures & additive,

Type G—Water-reducing, high range, and retarding admixtures & additive.
