Can i drill anchors in to this concrete ?

Hi all. Instead of just concreting a timber post in to the ground, can i pour the mix in to a hole wait for it to set fully and then drill anchors in to the concrete?
Asked by: Anthony85

Use of quick set. concrete

Can 2/3 bags be used in one go , I need to set more than a small thickness ?
Asked by: Bigcack01

Mold

I’ve been using this but when it dries up, it leaves salt crystals/mold around it. I try wet it with water and it still comes back. How do I get rid of this?
Asked by: Tals

Plasticiser required?

Does this need plasticiser adding to it for repointing some brickwork? I will use a 5-1 sand/cement mix as it is a Victorian brickwork and want a sandy colour finish.
Asked by: StevenBirmingham

Can you drill this to accept concrete bolts?
