Grout Pumping and Injection Operations TR 003 DEFINITIONS Portland cement Type HE (High Early Strength), the base material of the grout. Type HE cement is finer than GP (General Purpose) cement and has advantages of improved penetration, faster setting and higher early strength. Groutaid ® An additive, used to improve the overall properties of the grout including stability, flow, penetration and strength. SP-40® A super plasticising additive, used to aid the dispersion of cement particles, i.e. separate them, to maximise flow of the grout for a given water content. This enables the production of fluid grouts over a wide range of water/cement ratio. “Blocker” grout (in two parts Cmax™ & Thermax™) is a controlled-set, 2-part, mineral cement used as a blocker or quick setting agent.
