CG polycarboxylate water-reducing agent is currently the most-edge, high-tech, promising in application, and overall best-performing high-performance and high-efficiency water-reducing agent. The product features a high water reduction rate excellent slump retention, and significant strength growth, reaching today's international advanced levels in terms of technical performance indicators and cost-effectiveness.

I. Performance Characteristics

1. Low and high water reduction rate: The water reduction rate can be as high as 35%~40%, making it suitable for preparing high-strength and high-performance concrete

2. Low slump loss over time: The 1-hour slump loss of ready-mixed concrete is zero, which is extremely beneficial for the long-distance transportation and pumping of commercial concrete, ensuring the workability of the concrete without affecting its normal setting.

3. Good concrete workability: Concrete prepared with polycarboxylate water-reducing agent will exhibit obvious segregation or bleeding even under high slump conditions, and the appearance color of the concrete is uniform. This is extremely beneficial for preparing high-fluidity concrete, self-level concrete, self-compacting concrete, and fair-faced concrete. When used to prepare high-grade concrete, the concrete has good workability and cohesion, making it easy to and pour.

4. Wide cement compatibility: It has excellent compatibility with different types of cement and admixtures, solving the compatibility problem between other types of water-reducing agents anditious materials.

5. High strength growth rate: It has a high strength growth rate, including a high early strength growth rate, improving shrinkage performance and reducing the carbonation rate concrete. The 3~7 day compressive strength ratio is 160~170%, and the 28-day strength ratio can be as high as 45~155%, with performance indicators higher than similar products.

6. Low concrete shrinkage: It can significantly reduce concrete shrinkage, markedly improving the volume stability and durability the concrete.

7. Extremely low alkali content: Alkali content ≤0.2%. The product has good stability: no precipitation occurs at low temperatures.

8. Green and friendly product: The product is non-toxic and harmless, making it a green and environmentally friendly product conducive to sustainable development.

II. Technical Performance

Physical properties: Appearance: yellow liquid, non-toxic, odorless, non-flammable. Content: 40%.

Chemical properties: pH value: 6.5±0.5; sulfate content ≤0.5%; chloride ion content ≤0.2%; total alkali content ≤2.0% (calculated on a solid content basis). The cross-linked branched in the molecular structure of polycarboxylate-based water-reducing agents continuously releases water-reducing agent molecules during the cement hydration process to maintain the dispersing and slump-retaining properties of the water-reducing agent.

III. Instructions for Use

1. The dosage of CG polycarboxylate water-reducing agent is 0.2% to 0.5% the total weight of cementitious materials. A concrete trial mix test should be conducted before use to determine the optimal dosage.

2. CG polycarboxylate water-reducing agent must not mixed with naphthalene-based high-efficiency water-reducing agents.

3. When using CG polycarboxylate water-reducing agent, it can be added directly in its original liquid or prepared into a solution of a certain concentration for use.

4. Due to the high water reduction rate of concrete mixed with CG polycarboxylate water-reducing agent, the slump highly sensitive to the amount of water used. Therefore, the water content must be strictly controlled during use.

5. CG polycarboxylate water-reducing agent has good adaptability to the majority of cements, but for some specific cements, there may be phenomena of low water reduction rate and high slump loss. In addition, the fineness and storage time of the cement also affect the effectiveness of CG polycarboxylate water-reducing agent. In such cases, it is recommended to appropriately increase the dosage or blend with other
