MasterRoc MP 800

MasterRoc MP 800 is a well graded cement milled from pure Portland cement clinker with a Blaine value of 800 m2/kg. Due to its small particle size, it penetrates tight joints, fissures, and pores very well to provide a water-tight grouted rock or soil mass. It achieves initial and final setting faster than standard micro and ultrafine cements. This increases the productivity in injection operations. The short open time of 1 to 1½ hours and a very short setting time of 2½ hours (at about 20° C) reduces the waiting time for the next excavation round to a minimum.
