Conbextra STD, multi purpose cementitious contuction grout, is supplied as a ready to use dry powder. The addition of a controlled amount of clean water produces a flowing grout. Additives impart controlled expansion characteristics and reduce the water necessary to give a fluid grout. The grout can be used up to 100 mm thick.
Conbextra STD is a blend of portland cement, graded filters and chemical additives which cause controlled expansion in the plastic state. By minimising the amount of water added a non shrink mortar can be produced. This will be suitable for bedding of concrete precast units to provide positive connection between elements.
