Fiber-reinforced cementitious matrix (FRCM), also called textile-reinforced mortar (TRM), is a thin structural layer which combines specially designed mortar with carbon or glass fiber grid reinforcement. It is an economical solution exceptionally suitable for repair and strengthening of historical structures.
FRCM Systems Have Many Advantages
- Quick and easy installation requires less preparation than traditional FRP strengthening and also ensures minimal downtime
- Cost-effective solution compared to traditional concrete strengthening
- Does not add significant weight or mass to the structure, which makes it ideal for historical buildings and structures
- Outstanding performance for strengthening irregularly-shaped structures and substrates
Sika’s FRCM Systems Come in Two Types
1. Carbon Fiber Grid Reinforcement
A patented carbon-fiber grid embedded in a specially designed repair mortar for the reinforcement of concrete or masonry structures.
Features:
- Reinforcement of structures in damp environment and up to 80 °C (176 °F)
- Enhancement of tensile strength in two directions (bidirectional)
- Easy and fast to handle and to apply, less waiting time after concrete repair
- No UV protection required
- Better behavior in case of fire
