Description:

TamCrete MFC and TamCrete SFC are Microfine Portland cements for rock injection. The superfine particle size, together with the addition of TamCem Superplasticisers, provides superior penetration into tight joints, fissures, thus providing a water-tight grouted rock mass.
TamCrete MFC and SFC are ground from pure Portland cement clinker to achieve a Blaine surface value of > 625 m²/kg.
All grades of our TamCrete MFC and SFC achieve initial and final set faster than OPC, which reduces the waiting time to a minimum for the next activity to start. This increases productivity in a tunnel grouting operation. The initial set time can be adjusted depending on the level of TamCem superplasticiser or TamCem HCA added to the mix.

Features:

• Standard cement injection equipment can be used
• Superior penetration into rock fissures
• Fast initial gel and setting
• Higher strengths achievable than with chemical grouts
• Greater penetration imparts greater water tightness
• Better working environment and no hazardous
  components
• Durable
• Economical solution

Uses:

• Rockmass grouting for tunnels, caverns, mines, etc., used for pre and post excavation injection. Ground water sealing and ground stabilisation.
• Soil Injection: Ground stabilisation, ground water sealing
• Concrete crack injection
• Consolidation of weak and fractured rock
• Sealing of water channel
