Injection Cement

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.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

TamCrete UFC range of ultrafine cements are OPC based (UFC Fine) or incorporate selected granulated blast furnace slag and Portland Cement as an activator (UFC Ultra and Xxtra). TamCrete UFC cements are ideally suited for permeation grouting into soils due to their fine particle size or injection into tight rock formations.
> Standard cement injection equipment can be used> Superior penetration into soils> High stability> High resistance against chemical attack> Better working environment and no hazardous components> Durable> Economical solutionTYPICAL APPLICATIONS> Soil consolidation and stabilisation> Increasing soil bearing capacity> Rock fissure grouting> Forming water cut off barriers in soil> Concrete or masory repair> Underpinning 

TamPur 116T is a two-component, silicate modified, solvent-free, semi-flexible polyurethane injection resin. It is specifically designed for rapid strata consolidation in poor soft ground geologies in hard rock mines and tunnels, providing structural integrity, strength and some flexibility. Its superior performance allows TamPur 116T to be used as a Chemical “Rock Bolt Resin” and on-site tests have demonstrated pull-out strengths in excess of 31 tonnes.KEY BENEFITS
> Non-foaming even in contact with water and will not absorb water> Penetrates cracks wider than 0.25 mm> Shows good adhesion to wet substrates> Fast reaction even underwater> Fire resistant> No agitation of components required beforehand> Low odour> Environmentally friendly> User friendly
