Concrete repair mortar 25kg CERESIT

CD 26 is a high-quality one-component cementitious mortar designed for the repair and restoration of concrete and reinforced concrete. Thanks to its coarse-grained structure, the mortar is ideal for application in thick layers from 30 to 100 mm, with the possibility of a single application of up to 35 mm. Reinforced with fibers and modified with polymers, CD 26 provides exceptional strength, water resistance and resistance to aggressive atmospheric and chemical influences.

Areas of application:

• Repair of cracks and cavities in concrete
• Restoration of structural elements: balconies, overpasses, bridges, overpasses
• Repair of concrete tanks, pools, frame structures and ditches
• For emergency repairs in case of mechanical damage or corrosion
• Ideal for industrial and infrastructure sites exposed to stress and aggressive environments

Main advantages:

• For indoor and outdoor use - resistant to frost and de-icing chemicals
• It does not shrink, hardens quickly and has excellent adhesion to the substrate.
• Fiber reinforced for improved strength and crack resistance
• Waterproof and resistant to carbonation
• For manual or machine application (including shotcrete)
• Suitable for vertical and horizontal surfaces
• Compatible with all elements of the Ceresit PCC system (CD 24, CD 25, CD 30)
• One-component formula - easy to prepare and use

Technical characteristics:

• Compressive strength: ≥ 40 MPa
• Bending tensile strength: ≥ 9.0 MPa
• Adhesion to concrete: ≥ 1.5 MPa
• Temperature resistance: from -50°C to +70°C
• Consumption: ~2 kg/sq.m at 1 mm thickness
• Mixing ratio: 3-3.2 l of water per 25 kg of dry product
• Working time with the mixture: about 30 minutes
• Rain resistance: after ~24 hours
• Shrinkage after 28 days: ≤ 0.08%
• Compressive modulus of elasticity: ≥ 18 GPa

Method of application:

• Substrate preparation - the substrate must be clean, sound, rough and moistened
• Preparation of the solution - mix with water until a homogeneous mass is obtained
• Application - by trowel, pouring into forms or shotcrete
• Smoothing - with a steel or plastic trowel within 10-20 minutes
• Protection - if necessary, cover with fine mortar CD 24 or protective coatings CT 44 / CR 166
