KingRep SA300®
Spray applied, high build, one component, cementitious repair mortar for dry mix shotcrete application.
Overview
KingRep SA300 is a single component polymer modified and fibre reinforced repair mortar for dry mix shotcrete application. KingRep SA300 is a blend of dry powders, selected aggregates, reinforcing fibres, microsilica and high quality additives when mixed with water will produce a high build, thixotropic, highly resistant, alkali free repair mortar suitable for dry mix shotcrete machine spraying on vertical and overhead application. KingRep SA300 is to be applied using dry mix shotcrete spraying machines only.
Applications
- Large area repairs for all structural elements in buildings, water retaining structures, industrial plants, bridges, etc
- Repair of fire damaged structures
- Lining and repair of tunnels
- Cathodic Protection (CP) overlays
- Corrosion protection at marine areas when used in conjunction with Cempatch Primer M (cementitious bonding slurry and steel primer)
Advantages
- High early mechnical strength
- Shrinkage controlled polymer modified cementitious repair mortar. Reduces the risk of cracking due to shrinkage and ensures full contact with host concrete and load transfer in structural repair situations
- Easy to apply, single component, requires only addition of water
- Extremely low permeability to water, providing excellent protection to steel reinforcements and host concrete
- Thixotropic properties allowing extra high build for vertical and overhead applications
- Suitable for internal and external application
- Water vapour permeable
- Cost effective, spray applied no formwork is required
- Can be spray applied allowing for rapid application of large areas with minimal rebound
- STANDARDS KingRep SA300 complies with the requirement of EN 1504-3 as structural repair mortar of Class R4
- repair mortar for dry mix shotcrete
