CWC®SMARTCEM MC 40 is a single component cementitious, polymer modified repair mortar to provide high strength properties. This is used as a micro concrete material to repair damaged structural concrete especially in restricted accessible areas. It is based on cement, graded aggregates and special additives. CWC®SMARTCEM MC 40 can be applied in thickness up to 100 mm thickness. It is suitable to apply by trowel, knife, hand or pump. More Layer thickness can be achieved in repeated layers. It is used as a premixed mortar for concrete repairs and structural strengthening.
- Controlled expansion to ensure positive surface contact and low water permeability.
- Chloride and iron free, hence no rusting or staining on exposed edges.
- Pre-mixed, addition of water is only needed.
- Low permeability provides maximum protection against corrosion and carbonation.
- Easy to pour free flowing and self-leveling nature; it can be pumped or poured into restricted locations.
- Wear hand gloves, safety shoes and safety goggles while using and handling the product.
- In case eyes or mouth are affected wash with plenty of clean water and seek medical treatment immediately.
Before use, refer to the Material Safety Data Sheet.
