Microfine Injection Cement
Microfine Injection Cement
- TamCrete MFC is a Microfine Portland cement for rock and soil injection. Its superfine particle size, together with the addition of TamCem Superplasticisers, giving it superior penetration into tight joints, fissures and pore spaces, thus provide a water-tight grouted rock or soil mass.
- TamCrete MFC is ground from pure Portland cement clinker to achieve a blaine surface value of 650m2/kg.
- TamCrete MFC achieves initial and final setting faster than OPC and other microfine cements. This increases productivity in a tunnel grouting operation. The open time of 2½ hours allows for long distance pumping and a very short setting time of 3 hours reduces the waiting time to a minimum for the next activity to start (at about 20°C).
- TamCrete MFC is quality assured by the Cement Industry Quality Assurance Scheme, independently monitored by the British Standards Institute (SBI QAS 2420/47).
Key Benefits :
• 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
Typical Application
• Rockmass grouting for tunnels, caverns, mines, etc., used for pre and post excavation injection. Ground water sealing and ground stabilisation.• Soil Injection: Ground stabilisation and ground water sealing
• Concrete crack injection
• Consolidation of weak and fractured rock
• Sealing of water channels
