VELOSIT® NG 512
High performance non-shrink grout and flowable structural repair mortar R4
Product Description
VELOSIT® NG 512 is a high performance cementitious grout. It is dual shrinkage compensated for precision grouting applications and is non-metallic. VELOSIT® NG 512 can also be used as a micro-concrete. It is a R4 structural repair mortar according to EN 1504-3. It contains advanced corrosion inhibitors and offers high early & ultimate strengths. This product is formulated to be RCS (respirable crystalline silica) free and is manufactured using dust reduction technology.
Typical Applications
- Non-shrink grouting of machinery & equipment baseplates.
- Non-shrink grouting of structural steel & concrete column bases.
- Grouting of pre-cast concrete and filling of gaps between two concrete bodies.
- Structural repair / reinstatement of large area defects from 12 to 120 mm thickness. It can be extended for thicknesses greater than 120 mm, contact Hychem® Technical Service for guidance.
- Anchoring of a wide range of fixings such as anchor bolts, starter bolts and dowels.
- Can be used as a micro-concrete and for foundation re-builds.
