you need to have a ''keyway''---that is a groove in the base concrete,can be cut in if concrete has set,if not set,oil a 2x4lightly(lightly) & imbed it into the base concrete flush.
Do vinyl fence posts need to be set in concrete?
yes they need to be set in concrete. depending on your fence, one bag of concrete per post should be enough.
What is the setting time of concrete?
The length of time that concrete takes to set, will depend on the temperature. It would take approximately 4 hours for concrete to set at a temperature of 80 degrees.
How can you permanently retard fresh concrete?
Regular sugar will cause the concrete to never set.
How do you soften concrete?
you can't once set.
Why does a flash set happen in concrete?
A flash set can occur in concrete when the cement mixture hardens rapidly due to factors like high temperatures, improper mixing, or the use of certain additives. This can result in decreased workability and potentially compromise the overall strength and durability of the concrete.
Why 2 gypsum is added in the cement?
Gypsum is added to cement to control the setting time of the cement and prevent early hydration, which can affect the workability of the concrete mixture. It also helps in preventing flash setting and cracking in the final concrete structure.

What is the best method to prevent tile debonding?
This answer pertains to tile set on a concrete substrate! Assuming your thin-set is properly mixed with correct water ratio, the substrate is free of any bond breakers, and it is troweled for the type of tile your using, the most common problem is moisture coming up through the slab collecting at the tile/substrate interface. If you are in a humid climate the HVAC will pull moisture out of a concrete into the less humid interior. Water breaks down the thin-set bond to the tile and emulsifies other mastic's/glues intended to secure a VCT product. The best way to prevent moisture from wicking through a slab is to waterproof the concrete substrate with a product that will will stop this moisture transfer. It will also prevent the alkali in a concrete from coming out to a surface where it reacts with an atmosphere. Alkali burn causes a paint to bubble, peel and blister off a concrete. With a waterproofed concrete this alkali does not migrate out and form efflorescence salts. When you stabilize concrete, contaminates don't enter and moisture doesn't travel to a surface.
