Five Star Construction Grout AGE Five Star Construction Grout is a premixed cementitious grout developed for application where an economical shrinkage compensated grout is required. AGE Five Star Construction Grout is based on specially selected cements, graded aggregated and admixtures including special  patented mineral expansive agent. This special formulation produces a grout which is non-shrink by ASTM C827 "Early Volume of Cementitious Mixtures". It does not contain iron, aluminum or other additives which produce non-shrink characteristics by chemical reaction. This eliminates any subsequent problems of dimensional instability, corrosion or staining. AGE Five Star Construction Grout is designed to be placed either head pressure or pumping techniques. A trowel able consistency mortar can also be mixed. Download the data sheet and the MSDS below : Data Sheet MSDS
