Polycarboxylic acid anti-cracking waterproofing agent (KH-K) The main components are polycarboxylic acid water reducing agent and auxiliary polyol, water-repellent component, shrinkage reducing component and alcohol modification component It can reduce the water permeability of concrete under hydrostatic pressure, improve the impermeability of concrete, and improve durability. Polycarboxylic acid anti-crack waterproofing agent implementation standards GB8076-1997 “Concrete Admixtures”, GB50119-2003 “Technical Specifications for the Application of Concrete Admixtures” and JC 474-1999 “Mortar, Concrete Waterproofing Agent” standard.

Polycarboxylic acid anti-crack waterproofing agent product features:

1. Dosage: 1.5~2.5% of the total gelling material.

2. Water reduction rate: 12~20%.

3. Adding polycarboxylic acid anti-crack waterproofing agent can significantly improve the workability of concrete and increase the initial slump; it has better slump retention ability and is suitable for transportation over a certain distance.

4. Effectively inhibits initial hydration heat release and can be applied to large-volume concrete.

5. The anti-permeability grade of mortar can reach P8~P10, and the anti-permeability grade of C30 concrete can reach P14. The maximum impermeability level of the prepared concrete can reach P40.

6. Green and environmentally friendly: no harmful substances such as formaldehyde are used in the synthesis process, and no pollution is caused to the environment.
