NC-D15 alkali-free liquid, accelerator
NC-D15 alkali-free liquid quick-setting agent is a high-performance, alkali-free liquid quick-setting agent suitable for wet spraying and dry sprayed concrete, which can accelerate cement coagulation hardening, improve the early strength of concrete, small strength loss in the later stage, non-toxic and odorless, non-combustible and non-explosive, and no rust on steel bars. The solid content of this product is 50%.
Product FeaturesApplication Scope
Product Features
- Alkali-free: reduces the risk of alkaline aggregate reactions and reduces the loss of final strength of shotcrete. Improve the durability of concrete and can be applied to permanent support.
- Quick-setting: Incorporating this quick-setting agent can make the setting time and strength of shotcrete meet or exceed the requirements of national standards, which is conducive to accelerating the construction progress.
- Economy: Replace the double-layer construction mode of “first support, then lining”, which can reduce the thickness of support and save engineering investment.
- Environmental protection: There is little dust generated in shotcrete construction, providing a good underground working environment. This product is non-corrosive, greatly improving work safety and reducing environmental impact.
Scope of Application
- NC-D15 alkali-free liquid quick-setting agent is especially suitable for shotcrete with high durability requirements, primary spray layer thickness, and high strength in the early and late stages.
- Its scope of application is: tunnels, passages, caverns, shafts and mines, permanent and temporary rock support, slope support, concrete structure repair.
