VELOSIT® RM 208
High Strength Structural Concrete Repair Mortar R4
Product Description
VELOSIT® RM 208 is a microsilica enhanced cementitious repair mortar that is mixed with water to become an R4 structural repair mortar according to EN 1504-3. It is used to fill large voids or build up larger cross-sections up to 50 mm. VELOSIT® RM 208 is a shrinkage compensated cementitious repair mortar with quick strength development. VELOSIT® RM 208 is based on a complex formulation of mineral and organic identifiers and additives. It’s optimized grading allows for a very dense packing, which improves the cohesiveness and watertightness. VELOSIT® RM 208 creates an extremely well bonded, rigid abrasion resistant layer on the substrate. This product is formulated to be RCS (respirable crystalline silica) free and is manufactured using dust reduction technology.

- Overlays and repairs on concrete structures like dams, bridges, beams, balconies, facades.
- Application on horizontal and vertical incl. overhead areas.
- Application thickness from 6 mm to 50 mm.
- Used as micro-concrete.
- Can be applied by trowel or suitable spray equipment.
Features
- Minimal shrinkage/expansion under dry resp. wet curing conditions minimizing the risk of micro-cracking.
- Fiber reinforced.
- 60 min. working time and extended finishing window.
- Final strength of more than 65 MPa after 28 days.
- Excellent adhesion to properly prepared concrete.
- Good resistance against CO2 and Chloride penetration due to a very tight pore structure.
- Good resistance against aggressive media with a pH range of 3-12 and against soft water with low ion content.
