    I need to put in a angle iron post, into a concrete block at the end of a driveway. I just checked, blocks are upright and just full of sand and dirt. It rained last night pretty good. Maybe a couple days to dry out? Looking at small amounts of pre mix concrete to use for the sign posts, maybe 6-8" deep. I have local Home Depot and Lowe's. most of the pre mix says it is good for inside and out. I guess this pre mix is most for tile work or repairs.

    Guess I should have said, never worked with concrete before, nor do I want a big bag and wheel-bower to drag around. It is two 6 ' zinc plated angle iron with a not an exit sign between on a chain. Not my idea, just stuck having to do it. So maybe a foot deep??

    You can dig a hole sink the post a little way into the ground and then pour the dry mix around the leveled post. Cover with dirt. It will draw moisture and set without mixing. If you have to use the blocks. Pour a pile of mix on a piece of plywood, make a hole in the center of the pile, pour a little water in and start mixing. Should be on the dry side. Pour the mix in the holes and you are done. One bag should do it I would think.

    Not sure if I am seeing in my mind correctly what you are describing but I have planted my fair share of posts with concrete. I would think you will need a little more substantial base unless concrete blocks are already cemented in. Either way I would find a five gallon bucket for the mix and add some gravel to the mix to support a post . Are you talking about those little tubs of premixed cement? For a post I would think u would need about a foot to a foot and a half of support by adding the gravel it will make it stronger a go farther as far as volume of material needed to support the post. Pm me if I am misunderstanding what you are trying to accomplish

    The concrete blocks are at the end of a driveway for 3 houses, off a a main street. Now I am thinking of cleaning out the dirt, position the post in the hole ( 4 x 5" about) and pour the dry mix in and water. Now we are talking dry mix bag, probably better than small pre mixed stuff. I can use the remainder around my house. gravel I have already. spare 5 gallon bucket. yep, I got this now. thanks, ran

    I would say you want to be closer to 2 feet down for enough support that you're not having to reset the sign after a stiff wind storm. Also, depending on your location, you may also want to consider the impact snow will have on the installation.

    You can buy the stuff from depot or lowes that has everything required except for a mixing drill, mix it and pour it.

    I am in the Pacific North West with 40"s in the morning right now. 6' iron, OK, about 2' in the ground. Two poles and a small sign on the chain between. This way ,little problems with the winds. again, not my design.

    Well, I can go down about 11" only. I'll try to dig further (this is inside the block). If I can't, maybe cross nut/bolt at the bottom of the steel??

    I missed the part about the block. I think that should be fine. I also thought the sign was on the post not on the chain between them. ~1 foot should be fine.

    I managed to dig down a bit more. Fun inside of the block, knuckles love it. I think the nut/bolts in the post is worthwhile.

    Most fun, the 80 lb bag at Home Depot, then I saw the 50 lb bag of fast setting and got that. The actual work went fast with this 20 minute fast setting. Did I say I am 62 yrs old? I feel it. Will set up the chain and sign tomorrow.

    Just remember for the future, fast set concrete has a lower strength than regular. Wont really make a difference if you are setting a letterbox inside the hole of a preformed concrete block tho but for jobs that actually require good structural integrity its something to keep in mind.

    Do a big concrete job and you will add 20 years to that. I just finished doing a slab for the back of our shed. Worst bit is always barrowing across the mesh.
