ACG Anti-Corrosive and Shrinkage Compensation Grout
 
ACG(Anti-Corrosive and Shrinkage Compensation Grout) is a grout material containing a special rust preventive agent to prevent corrosion of steel. It is a grout material that exhibits superior rustproofing performance compared to ordinary grout materials. The ACG has general type and anti-washout type
 
· Characteristics
- Excellent flowability
- Excellent rebar corrosion protection by containing anti-corrosive ingredients
- High strength
- Excellent adhesion to rebar, metal and concrete
- Construction is available even in moist areas
- Excellent penetration blocking performance to harmful substances such as moisture or salt
- Moisture-hardening type
 
· Use
- Grouting of slope anchors, rock bolts, etc.
- Grouting where corrosion protection of steel is particularly required
 
※ Patent No. 10-1235641
