Frequently Asked Questions about ALKALI RESISTANT GLASS FIBERS
Q: If i grind to expose aggregate, will these glass fibers show in the surface?
A: It's so hard to stamp concrete with one flexible mat. You can use flexible mats, but I would recommend to use at least 3-5 mats.
Yes, glass fibers will show up on surface if you’ll grind concrete surface unless you mix two batches and line your mold with about 1/2 to 3/4 in of the batch without the glass fibers. Also depends if you are doing cast in place or inverted. You can also torch the the alkali resistant fibers after grinding.
Q: How much glass fiber i need for gfrc concrete countertop casting?
A: It really depends to your preferences or casted product, but average alkali resistant fibers to GFRC concrete ratio is between 1 to 3% by total concrete weight. For 100 lbs of GFRC concrete you need between 1 to 3 lbs of glass fibers. Always make a test prior casting actual product. Standard concrete ratio 1 1/2 to 3 lbs per cubic yard.
