Answer: 
Yes, easily. And since 5 gallons is 90 lb of concrete, you only need 1 90 lb bag.

Answer: 
Yes, but the bucket will crack and not last as long as the concrete and stake. Lifting the bucket with its handle after the concrete is hard may be a bit heavier than you think. So if you want it to be portable or something, you will eventually just have to grab it by the stake or the concrete to move it around.

Answer: 
I don't know why not. Considering the volume of a five gallon bucket, you would probably need 2 bags of quickcrete. You might want to also drill some holes in the stake and put something like a rod or bolt through to keep the pole from coming out of the concrete.

For a thickness of 1/2-1 inch, you can use QUIKRETE Sand Topping Mix blended with QUIKRETE Concrete Acrylic Fortifier #8610 replacing a portion of the mixing water.

Answer: 
No, not without help. You will need to look for a bottle of concrete bonding adhesive or bonding agent. I've done this before, but the recommendation is to use a thinner setting concrete. Read the labels and find the concretes that say they are for thin, tapered slabs, like down to 1/4 inch. Those will have almost no aggregate and they are expensive in large quantities. Might want to hire someone.

I have used this produce in the same type of weather to make support blocks 16x24x8 above ground--But I protected it from freezing overnight with the use of insulation blankets. No harm seemed to be done to the blocks--but you are taking a chance.--If it freezes before it cures and the moisture is out it will crack.

Answer: 
YES, definitely YES! This type of concrete has accelerators and it will do well because of the self-heating aspect of it. Do not dilute it in cold weather with regular concrete. Use it just as the instructions on the bag say. Don't get it too wet. You could substitute hot water for cold water and it will help a little.

Yes - However, in cold weather, which, for the purposes of concreting, may be considered to be weather that is below 50 dF, or near freezing 32 dF at night, it is important to take certain precautions: 1) Mix the concrete with water before placing the material in the hole, 2) store the bagged concrete in a warm temperature before use, and use warm water to mix, 3) protect the concrete from freezing for at least 48 hours for QUIKRETE Fast Setting Concrete Mix using plastic sheeting, insulated blankets, or other means. If these preventive measures cannot be taken, it would be best to wait for warmer weather. In weather above 50 dF, if pouring the QUIKRETE Fast Setting Concrete Mix into the hole dry, place the material in lifts of 2' 6” or less, adding the appropriate amount of water for each lift, to allow water to soak all the way through. Using a shovel to “chop” the material in the hole will help distribute the water. Read Less

A 50 lb bag of QUIKRETE Fast Setting Concrete Mix yields approximately 0.375 cubic feet of concrete. A 17 ft x 1 ft x 2 ft trench would require approximately 34 cubic feet of concrete, or approximately 91 50 lb. bags of concrete. An application like this requires that the material be mixed with water before being placed. It can only be placed dry followed by the separate addition of water on top of it Read More

The Quickcrete 50 lb. fast-setting concrete mix is not meant to be used on large projects. From the time you begin to mix it to the time it is set is 20 - 40 but I have seen it set in less time. 15 - 20 minutes. Fast-setting concrete sets fast enough that it probably won't adhere well to the previous batch, causing weak points along your entire project.

Fast-setting concrete sets fast enough that it probably won't adhere well to the previous batch, causing weak points along your entire project. Can you pour it all into a trench and then add water? Maybe, but you need 1 gallon of water for each bag and that measurement is pretty precise. Not enough and it will crack and flake, too much, and it won't set. You would need least 90 to 100 bags. of concrete and 90 to 100 gallons of water to do the job you are describing. Read Less

Rated 4.3 out of 5 by 36 reviewers.
Rated 4.0 out of 5.0 by Turned my weekend project into a one day project.......awsome Used this to set in 4x4 pressure treated wood that were to be used as fence posts. I love the stuff. Now I dont put up a lot of fences, nor do I use a lot of concrete, but this stuff was easy to use and worked very well for my application. The reason I gave 4 stars instead of 5 is because 2 out of the four bags has some concrete in them that was unusable. Like it had gotten wet and some of the concrete in the bag was solidified already. Other than that. The stuff dries fairly fast and holds strong. Made a weekend project into a one day project which is great in my book. Steak in the 4x4 so that they remain straight. Pour dry mix into the whole then pour in enough water to penetrate all of the concrete and wallah move on. Its great. No need for premixing unless that is just what you want to do. May 18, 2016
Rated 2.0 out of 5.0 by Works well, but may not get all you pay for Recently bought 5 bags of this from the El Cajon store. Used it the next day and found that four of the five bags had portions of the cement that was already rock solid and not usable. This store has the cement outside and I don't know if this is why this happened. The portions I was able to use worked as advertised. I will either get it from another store where it is stored inside, and make sure is it all loose, or pick another product. November 9, 2015
Rated 4.0 out of 5.0 by Works well but always mix prior to pouring Never pour in dry and add water afterwards, always a possibility it will not penetrate all material and set properly, buy a spade and cement tub for a few dollars and mix the cement before pouring and do not wait to long, it starts to harden fast. Again, make sure to mix before use, directions say you can pour in dry and add water but save yourself a possible headache and mix prior before use. Otherwise product works fine April 3, 2016
Rated 5.0 out of 5.0 by Lars recommended the higher priced item because it would dry quickly and since we are installing posts.. Sakrete is a good product and my salesman recommended a faster drying product. March 16, 2016
Rated 5.0 out of 5.0 by GREAT My Jack Russell dug a large hole in front of my chain link gate. it took the hole bag to fill it up. I used hot water since the temperature was 41. It set up in 30 minutes. Just like any other thing I get from Home Depot it was a great product. exceeded my expectations. Definitely will buy more when needed. January 1, 2016
Rated 5.0 out of 5.0 by Note.... I have used this product several times in the past. After adding water take a piece of rebar or a sturdy stick and push down into the wet mix, moving it around a little. this helps the water reach all parts of the mix. Not a full stir, just a wiggle or two. January 3, 2016
Rated 5.0 out of 5.0 by Worked as indicated on bag I purchased this product after my stockade fence fell during a storm. The previous owner of my property set the poles in sand so of course that didn't withstand much wind. I didn't want this to be a major project spanning multiple days so I jumped at the possibility of quick set no mix concrete. The day I used this product it was 34 degrees outside so I did as directed and added hot water in the quantity indicated. After putting tools away ,I took a shower and changed clothes. In that amount of time (approx 45 mins) it had set solid .. I'm very happy with this product for the use described, note however that the finish was rocky since there was no need to smooth it for a finished look since I covered it with dirt after photo but for setting poles the red bag product works great. November 26, 2013
Rated 1.0 out of 5.0 by No good The concrete mixes are made with rock that has been dug up out of the ocean and its not washed like they claim and the salt breaks down the integrity of the concrete over time and it gets brittle and will loose its strength. November 18, 2015
