MasterCrete CI 5300

Lightweight Polymer-Modified Mid-Strength Repair Mortar with Corrosion Inhibition (formerly MasterEmaco S 5300CI)

How Does MasterCrete CI 5300 Work?

MasterCrete CI 5300 is a single-component, lightweight, polymer-modified, high-build structural repair mortar with active corrosion inhibition. MasterCrete CI 5300 has been specifically formulated to produce a mortar with the compressive strength and modulus characteristics defined in class R3 of EN 1504 part 3.

Recommended Uses:

MasterCrete CI 5300 is used for the structural repair of lower-strength concrete elements such as:

• Balcony edges, soffits, and decks

• Window ledges, lintels, and beams

• Any concrete structures that need to be repaired or re-profiled by hand

What Makes MasterCrete CI 5300 a Unique Solution?

MasterCrete CI 5300 allows the repair of medium-strength concrete without problems of differential movement due to its medium strength and lower modulus of elasticity properties. It contains active corrosion inhibitors.

What Are the Benefits of MasterCrete CI 5300?

• Shrinkage compensation and fibre reinforcement - minimise crack tendency creating a longer lasting repair.

• Highly thixotropic and lightweight - allows single high build layers.

• High build - applied up to 75 mm in vertical applications and 50 mm overhead.

• Outstanding workability - easy to create profiles and corners without formwork.

• Very low shrinkage - excellent crack resistance.

• Durable and weather resistant -  Good water and chloride impermeability.

• Low chromate (Cr[VI] < 2 ppm ) - low risk of skin irritation.

• Chloride-free - does not add to chloride load of contaminated structures.

• Active corrosion inhibition – suitable for extreme environments.

• Approved to AS/NZS 4020:2018 (tested to the maximum exposure level) - suitable for contact with potable water.
