XPERT Expanding Grout


XPERT Expanding Grout

Plasticized Expending Grout Admixture

XPERT Expand Grout is an admixture for cementitious grouts where reduced water/cement ratio and positive expansion is required. The Expanding agent, by generating gas during the hydration process before the initial set takes place, counteracts the natural settlement and shrinkage of the grout. The Plasticizing agent enables high workability mixes to be produced with relatively low water/cement ratios stability and cohesion of the grout are greatly increased. The expansion is controlled to avoid excess being built up.

• Positive expansion ensures permanent contact and high bound to entire grouted surfaces. • High compressive strength Obtained with low water cement ratio. • Improved quality assists productions of grouts free from water pockets and bleeding. • Microcellular grout structure Combined with reduced water/cement ratio, provides improved resistance to both frost and fire damage. • Iron free no metallic iron content to corrode and cause staining or deterioration due to rust expansion in the grout. • Chloride Composition allows high early strength development in grouts without the use of chlorides.
Applications include bed grouting, duct grouting, non shrink in-filling and jointing, pressure grouting for tunnels and shaft linings.
