4. Polycarboxylic acid high-performance water-reducing agent Ming
The product is a water-soluble composite water-reducing agent with carboxylic acid-based substances grafted on high molecular polymer as the main body. Incorporating this product can greatly improve the fluidity of concrete, allowing the concrete to maintain construction performance for a longer period of time. It can also improve the workability and physical and mechanical properties of concrete and improve the quality of the project. The strict quality control system makes the quality stable and has reached national standards.
Product Features
The compatibility of various cements is good, the slump maintenance performance of concrete is good, and the construction time of concrete is extended.
The product has low chloride ion content and low alkali content, which is beneficial to the durability of concrete.
The product production process is pollution-free, does not contain formaldehyde, and complies with international standards for environmental protection management. It is a green and environmentally friendly product.

Usage
Dosage range In general, the recommended dosage is.
Polycarboxylic acid high-performance water-reducing agent cannot be mixed with naphthalene-based high-performance water-reducing agent. When using polycarboxylic acid high-performance water-reducing agent, the mixer and mixer truck that has used naphthalene-based high-performance water-reducing agent must be rinsed clean. Otherwise, the water-reducing effect may be lost.
It is recommended to conduct a mix ratio test before use to determine the optimal dosage.
Packaging and Precautions
Liquid products are packaged in drums or square drums or as required.
