Glass fiber reinforcement in thin slab mix???

Drake · 04-25-17, 01:13 PM

Any opinions or knowledge of glass fiber in a thin slab mix for fracture prevention in a radiant hydronic floor being a poor choice? Glass is a good heat conductor as windows prove. My thin slab will also have rewire in it to secure hydronic tube to. I like how fibers have performed in other concrete floors I have done. Slab does not need to be light weight material(subfloor designed to hold it). Joists on 9"cc to fit pole barn steel siding subfloor which has 9"cc formed ridges.
