MasterRoc MG 01
High yield thixotropic cable bolt grout
Description:
MasterRoc MG 01 is a high yield, shrinkage compensated and thixotropic grout for placement of cable and rock bolts in civil tunnels and underground mines.
Recommended Uses:
MasterRoc MG 01 is particularly suitable as a grout used for the encapsulation of roof bolts and cable anchors where the “top-down” grouting method is preferred. MasterRoc MG 01 has been specially developed to give a high yield (volume) of grout without segregation or bleed whilst providing excellent compressive strengths.
Features and Benefits:
Extremely pumpable but shows rapid thixotropy to restrict flow into surrounding strata
Economical to use, due to high yield and rapid thixotropy
Small grout tube diameters mean smaller diameter drill holes can be used
Eliminates the requirement for sealing of the collar and plate with cotton waste etc
Good ultimate strength to ensure the permanence and safety of critical installations
Extended working time (over 30 minutes at 20°C) enabling easier cleanup of pumps and hoses
Shrinkage compensated for greater bond strength to surrounding strata
High bond to steel
