I use it for filling holes I don’t think is working on this .The broken concert will open again time after time. I did a little broken concrete at my house with this a month ago look good for now but I’m not sure .
I used this stuff outside to anchor bolts into a brick wall with temps about 60F-70F. The setting time was extremely fast. Like a few minutes at most. FAST SETTING. After 2 minutes it is very hard.
No, it cannot be. Per the manufacturer's specficiations: Sika® AnchorFix-1 may only be used by experienced professionals. As a fast curing anchoring adhesive for all grades of: ▪ Rebars / reinforcing steel ▪ Threaded rods ▪ Bolts and special fastening systems Can be used on: ▪ Uncracked Concrete ▪ Solid masonry ▪ Hard natural stone* ▪ Solid rock* * These substrates may vary greatly, in particular with regard to strength, composition and porosity. Therefore, for each application the suitability of Sika® AnchorFix-1 Adhesive must be tested by first applying Sika® AnchorFix-1 Adhesive only to a sample area. Check in particular bond strength, surface staining and discolouration.
I would recommend a high heat thinset ot a synthetic such as this.
