Bonded Floor Slab (meaning concrete slab with a concrete overlay)
Bonded Floor Slab (meaning concrete slab with a concrete overlay)
(OP)
I am looking for design guides, or codes, on how to design a bonded floor slab. Anybody know anything about this?
This is a follow-up on my thread for concrete floor slab analysis, designed to support bus and truck lifting machines (with wheels that are so small, they overstress a standard slab).
Apparently bonded floor slabs are common throughout Europe where this lifting machine is in regular use.

Please elaborate.

Here is a link to a short US Army Corps of Engineers document on the subject (see Chapter 11):

This document does not mention presoaking with water - however if you can do this (overnight or longer) before placing the overlay, it makes a significant contribution to the bond strength.

I agree with SlideRuleEra's comments. Shot blasting or scabbleing provide the roughness, but cleaning of any coatings or oils on the floor is very important. We have used epoxy and latex bonding products as well as a cement/sand slurry.

How the layers will get bonded I have to find out, but not electrically.
