Sikacrete®-101 Standard CZ - Dry Sprayed Cementitious Micro-Concrete
Verified by manufacturer 1 day ago
General-purpose Class R4 dry sprayed cementitious micro-concrete with dust reduction technology for large volume repairs.
Application
Suitable for:
- Repairs of weathered, cracked, spalling and/ or damaged concrete structures such as tunnels, bridges, roads, cooling towers, walls, culverts, reservoirs, dams, floors of pools, etc.
- New construction.
- Concrete restoration (Principle 3, Method 3.3 of EN 1504-9): Restoring the original concrete to the originally specified profile and function. Restoring the concrete structure by replacing part of it by spraying concrete or mortar.
- Structural strengthening (Principle 4, Method 4.4 of EN 1504-9): Increasing or restoring the structural load bearing capacity of an element of the concrete structure by adding mortar or concrete.
Description
Sikacrete®-101 Standard CZ is a one-part repair mortar for dry spraying, containing cement, additives and graded aggregates with grain size up to 4 mm.
Sikacrete®-101 Standard CZ is a mortar with a 'normal' pot life and meets the requirements of EN 1504-3, Class R4. Reduced shrinkage enables it to be applied in thick layers by the dry spraying method, and dust reduction technology creates a cleaner, safer working environment.
Features and benefits:
- Economical.
- Large areas can be completed quickly and easily.
- High build.
- High cohesion with the substrate.
- Good workability with low wastage.
- Rapid strength gain.
- Class R4 according to EN 1504-3.
- Low shrinkage.
- Fast and easy application.
- Dust reduced for a cleaner, healthier environment.
- Low resistivity - can be used with cathodic protection systems.
- Overcoatable with Sika® reprofiling/ levelling/ smoothing mortars and coatings.
- CE Marking and Declaration of Performance in accordance with EN 1504-3.
