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.
