Plasticized Expanding Grout and Mortar Admixture

Strugrout ES500 is an admixture for cementitious grouts where a reduced water/cement ratio and positive expansion is required. Applications include bed grouting, duct grouting, non-shrink infilling and jointing.

Advantages

• Gaseous expansion system compensates for plastic shrinkage and settlement in properly designed cementitious grout.
• Reduced water/cement ratio mixes in the grout mix ensures low permeability and long term durability in service.
• Gives high grout fluidity with low water/cement ratio, thus making placement or injection of the grout easy.
• No metallic iron content to corrode and cause staining or deterioration due to rust expansion in the grout.
• Composition allows high early strength development in grouts, without the use of chlorides.
