Five Star Grout SP Five Star Grout SP is a premixed cementitious grout, developed for applications where an economical grout with good flow and retention of flow and higher strengths is required. Five Star Grout SP is based on specially selected Portland cements, graded aggregates and admixtures including a special form of carbon. This special formulation produces a grout which is non-shrink by ASTM C827 "Early Volume Change 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. Five Star Grout SP is designed primarily as a flowing grout but can also be used at trowel able consistency.
