Is there a limitation of grout with respect to temperature changes?

Hello Qian Zhang,
 
Thank you for reaching out to Hilti.
 
Yes, temperature affects an adhesive anchor system throughout its lifetime - from storage to installation and throughout the life cycle of an anchor. Temperature is an important factor which influences an adhesive anchor systems strength, cure time, ease of installation and creep performance.
 
Some adhesive anchoring systems are engineered for colder climates and others for warmer climates. High temperatures tend to soften adhesive materials, while cold temperatures might prevent a full cure of the adhesive. Both situations might lead to a reduction in bond strength. Each product will have a different low and high temperature threshold at installation and throughout the service life of the anchor.
 
Hope this helps.
 
Kind Regards,
