I am hoping for some feedback/advice on installation of a
fiber-reinforced grout topping in a clarifier which I designed.
I have specified that, after water blasting of the slab, a cement slurry
be troweled onto the concrete surface immediately prior to the grout
topping placement. The question has come up about a spec for the cement
slurry, and whether a bond breaker can be used in its place. The reason
for the specified surface prep is my understanding that a bonding agent
is not recommended because of the likelyhood of improper installation
leading to it acting as a bond breaker.
First, is there another successful method that should be used? And, if
a slurry is appropriate, is there a suggested mix specification. (I
should note that the specification was created using a standard spec
with a long track record, but I have learned again to not put a simple
material description in a spec without knowing exactly what is needed!)
Thanks in advance for any help.
