Adaptability and Uses
1. Perfect for early strength, retarded, precast, cast-in-place, flow, self-compacting, mass, high-performance, and faced concrete. Essential for industrial and civil buildings, especially low-grade commercial concrete.
2. Extensively applicable in high-speed railways, nuclear power, water conservancy, hydropower projects, subways, large bridges, expressways, harbors, and key national projects.
3. Vital for industrial, civil construction, and commercial concrete mixing stations.
4. Ideal for branch factories and long-distance transportation.
Usage Instructions
- This product appears as a colorless or light yellow liquid. Recommended Dosage Guidelines: Typically, 5%-30% of the mother liquor is mixed with other materials to create a water-reducing agent..For water-reducing agents, the recommended dosage is generally between 1% to 3% of the total weight of cementitious materials..
- Conduct adaptability tests with cement and gravel before using this product or altering cement and gravel types and batches. Tailor the water-reducing agent proportions based on test results..
- Use independently or combine with slow-release mother liquor to minimize concrete slump loss. For enhanced admixture properties like retarder/early strength/antifreeze/pumping, the application method and conditions should be confirmed via testing and compounding techniques.
- Use alongside other admixtures like early strength agents or air-entrainingagents, retarders, etc., ensuring preliminary testing. Avoid mixing with naphthalene series water reducers.
- Concrete Ensure the cement and mix ratio is determined through testing. During application, ensure water is added simultaneously in the concrete mixer. Conduct preliminary mixing tests to confirm concrete quality.
- For concrete with active admixtures such as fly ash and slag, calculate the water-reducing agent dosage based on the total cementitious material volume.
