CWC® SMARTCEM MC60
CWC® SMARTCEM MC60 is supplied as a ready to use blend of dry powders which requires only the site addition of clean water to produce a free-flowing non-shrink repair micro concrete. The material is based on Portland cements, graded aggregates and fillers, and additives which impart controlled expansion characteristics in the plastic state, while minimizing water demand.
- Dual shrinkage compensated – volume stable in wet and hardened state, reducing cracking tendency.
- No metallic iron content to cause staining.

CWC® SMARTCEM MC60 is supplied as a ready to use blend of dry powders which requires only the site addition of clean water to produce a free-flowing non-shrink repair micro concrete. The material is based on Portland cements, graded aggregates and fillers, and additives which impart controlled expansion characteristics in the plastic state, while minimizing water demand. The low water requirement ensures high early strength and long-term durability.
CWC® SMARTCEM MC60 can be applied in section up to 100mm 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. For larger repairs, the mixed SMARTCEM MC60 may be modified by the addition of 5mm to 12mm clean, graded, saturated surface dry aggregates at site.
- Dual shrinkage compensated – volume stable in wet and hardened state, reducing cracking tendency.
- No metallic iron content to cause staining.
- No bonding agent required – simple installation.
- Pre-packed material overcomes onsite batching variations.
- No vibration – fluidity allows placement without vibration.
- Develops high early strength without the use of chlorides.
- High ultimate strength ensures the durability of the hardened grout.
- Free flow ensures a high level of contact with the load-bearing area.
- SMARTCEM MC60 is alkaline and should not come
into contact with skin and eyes. Inhalation of dust
during mixing should be avoided. - Gloves, goggles, and dust mask should be worn.
Before use, refer to the Material Safety Data Sheet.
