High-Strength Non-Shrinking Grouting Material
1. Main Components
This product is an advanced cement-based grouting material composed
of high performance cement, aggregate, admixture and mineral additive. It is
divided into E and L types. E types base material is a quick setting, rapid
hardening and early strength cement, and type Ls base material is a
non-shrinking high-strength Portland cement.
