Case Study
VELOSIT® RM 203
Repair mortar for 1 - 100 mm, rapid setting – vertical overhead
Product Description
VELOSIT RM 203 is a rapid setting cementitious repair mortar for various types of construction substrates. It creates a good surface for coatings and overlays. VELOSIT RM 203 is a shrinkage compensated cementitious repair mortar with extremely fast strength development. VELOSIT RM 203 is the result of many years in the field testing and research. VELOSIT RM 203 creates an extremely well bonded, rigid, abrasion resistant layer on the substrate.
Typical Applications
- Repair of surface defects on concrete, masonry, many natural stones and steel
- Application on horizontal and vertical incl. overhead areas
- Filling of blow holes, honeycombs and surface roughness
- Application thickness from feather-edge to 100 mm
- Re-modeling of architectural features requiring a moldable mortar that can be shaved into shape
Features
- Product approved by TMR-QLD- MRTS72 + MRTS73
- Minimal shrinkage/expansion under dry resp. wet curing conditions minimizing the risk of micro-cracking
- Excellent workability especially overhead
- Fiber reinforced
- 10 min. working time & 14 MPa compressive strength after 2 hours
- Final strength of more than 50 MPa after 28 days
- Open to foot traffic after 1 – 1 1/2 hours
- Very good adhesion to properly prepared concrete & masonry
- Water curing only under hot & dry conditions required for 3 – 4 hours
- Good resistance against CO2 and Chloride penetration due to a very tight pore structure
