We provide non-corrosive structural fibers for concrete reinforcement, and some engineering support for projects. We have built many roads, railways, etc. without steel, and many in conjunction with steel, depending on the requirements. I would be happy to work with you to meet your...
It is generally accepted now that PP fibers--or PVA--will melt out during a fire and provide a sacrificial route for trapped water vapor to escape.
Steel fibers are great at reducing normal spalling, but they can cause dangerous explosions during a fire.
With PVA fibers you get a structural...
If the fly ash is reactive, you will gain long-term strength and durability by replacing cement 1:1 at 25% or more. I have seen replacements up to 66% that were very successful. To gauge the reactivity of FA, test it against the best and most consistent out there: Micron3 from Boral. (One...
Thanks for the response. These are good names, especially Denka, but I don't see any evidence that any of them are selling expansive cement, or grouts, or admixtures in North America.
I am trying to find non-shrink cement or an expansive admixture. Type K from Blue Circle seems not to be available. I heard about calcium aluminosulfate and gypsum, but I don't want to have to do a lot of blending and testing. Anything off the shelf?
