Parex LA Repair Concrete
Class R4, Flowable, High Strength, Deep Fill, Low Resistivity Cementitious Micro-Concrete
Parex LA Repair Concrete is a cement based, low alkali, one-component, high strength, deep fill micro-concrete with non-shrink properties. The mixed mortar produces a flowable repair mortar suitable for pouring applications meeting the requirements of Class R4 of EN 1504-3. Due to low resistivity, the Product can be used with cathodic protection systems.
- One-component, ready to use.
- Easy to mix and apply.
- Good early compressive strength (~20 N/mm2 at 1 day).
- High final compressive strength (~80 N/mm2 at 28 days).
- Non-shrink (in both plastic and hardened states).
- Repair depths up to 500mm in one application.
- Self-compacting (vibration not required).
- Uses aggregates which are not susceptible to Alkali-Silica Reaction (ASR).
- High tensile adhesion / bond strength negating the need for a bonding primer.
- Suitable for use in conjunction with cathodic protection (low resistivity).
- Low chloride content enabling it to be used in contact with steel.
- Can be placed under gravity or pumped.
- Reaction to fire: EuroClass A1.
