6.28 days free expansion rate 0.00-0.15%

7. Strength grades are divided into 32.5/42.5/52.5/62.5 four strength grades with 3d compressive strength

5. Packaging and transportation

25-50kg per bag, sealed and stored in a dry environment, the shelf life is three months.

After opening the bag, use it up at one time. Don't use it after it gets wet and agglomerates.

6.use

is mainly used in the GRC industry, high-end architectural jewelry, colored cultural stones, carving crafts, urban garden products, interior and exterior wall products, and various high-end porcelain sanitary ware.

7.matters needing attention

1. Do not mix with other types of cement;

2. Do not use other admixtures at will without testing;

3. After demolding, it can be cured with water only after the strength has developed to a certain level. It is best to use film for curing.
