Typically, you can apply some weight to the posts after 4 hours, but it’s a good idea to wait at least 24 hours before resuming fence construction. Standard concrete mixes may take up to two hours to set and should cure for 24 to 48 hours before any forces are applied to the posts.

Using a post-hole digger instead of a shovel to create your anchor hole is more effective, as it makes the perfect size anchor point.
