Admix GM515

Shrinkage Compensating Admixture for Production of Injection Grout for Post Tension Cables and Anchoring

                                   

ADMIX GM515 is a powder form admixture use to compensate natural shrinkage and bleeding, increase workability, waterproofing and increasing strengths of injection grouts. The product provides good adhesion to steel and is a suitable coating for steel cables against corrosion and rust. Using too much water for producing injection grout will result in excess of voids after evaporation, as well as natural shrinkage of grout up to 2-3 percent. Using ADMIX GM515 in the rate of 6% of cement in the grout can help to solve the problems.

Applications

ADMIX GM515 can be used for producing non-shrink and injection grouts at job site. Using this admixture in production of high quality and durable concrete is strongly recommended, especially in aaggressive environments and salty lands.

 

Expansion

Expansion affect occurs during 1 to 2.5 hours after adding the product in cement based mixes which depends on environmental temperature. The expansion rate is between 2% to 3% in cement based slurries, this rate is 1% to 1.5% in concrete or sand-cement mortars.
