Main performance characteristics:
1. The product has good water-reducing performance, and its maximum water-reducing rate can reach 30%.
2. This product is alkali-free and chlorine-free, and has no corrosion hazard to steel bars.
3. It has a strong dispersing effect on cement and improves the fluidity of mixtures. The slump of concrete can reach 18-22cm.
4. The concrete mixed with this product has less bleeding and no segregation than that of the reference concrete. The air content is moderate. A large number of tiny bubbles block the concrete capillary passage, which improves the frost resistance, waterproofing and durability of the concrete and makes the construction easier.
5. The density of the product is 1.10-1.15kg/L, the PH value is 6.0-8.0, and the solid content is 25-35%. There is no harmful chemical residue.
6. This product is added with effective anti-freezing components, which can effectively reduce the freezing point of water at low temperature and make concrete reach the critical strength of freezing as soon as possible. The compressive strength of concrete is greater than or equal to R28 (>100%), R-7 (>10%), R-7 + 28 (>100%) j, R-7 + 56 (>100%).
Recommended dosage and use method:
1. The dosage of cementitious materials is generally 3.0-6.0%. The specific dosage should be determined by experiments.
2. In general, mixing water is added into the mixer at the same time to mix until the prescribed time.
3. Immediately after pouring, cover the heat storage with two-layer thermal insulation material, and prevent frozen in the initial stage.
Packaging and storage:
1. Liquid products are packed in bulk or in barrels according to user's requirements.
2. Store in a cool and dry place to avoid direct sunlight.
3. The shelf life of this product is 1 year. The expiration date should be determined by test.
