Concrete floor hardener
Concrete floor hardener
(OP)
Does anyone have any experience with concrete floor hardener, metallic or non-metallic? Does it work? I am designing a slab for a dozer maintenance shop and there is going to be Cat D10's going across this slab with metal tracks. Should I use a hardener? Does it work? Is there something that would work better for my application?






RE: Concrete floor hardener
Floor hardeners work to a certain extent. They densify the top surface of concrete, and prevent small pits and tears that can quickly become larger due to abrasion across the surface. Shake on metalic hardeners increase the abrasion resistance of the top surface.
I'm not sure if anything is going work forever on a floor taking the kind of abuse your floor will.
I would talk to a sales rep from say L&M Chemicals (or others), they are pretty free to tell you all the wonderful things there products can do for you.
I would also consider using MM80 joint sealant at your control and contraction joints or reinforcing the slab enough to eliminate joints. MM80 will help suport the edges of joints and help prevent them from 'unraveling'. Joints are where a lot of the problems on these type of floors begin.
I once did a tank repair facility for the Army. I used hardeners, MM80 and the whole 9 yards on the slabs. Things were appearently OK for a few years until suddenly I got a letter stating that I had specified 'defective' floors. I went up to the facility to look at the floor. The slabs in a few of the bay were indeed in pretty bad shape. Many pits, gouges, spalling, etc. Come to find out the problem was if they couldn't get a tank into the bay under its own power, they hooked it up to a tank recovery vehicle and dragged it into the mainenance bay without the treads turning. Thats really good for the floor! LOL.

You need to be careful at your slab joints to prevent spalling there.

Also make the Client aware of what to expect from this slab. It will most likely chip and spall no mater what you do.
