I mixed it correctly, but today, two weeks later, its still moist and can easily be broken apart with your fingers. Ive used it before, but i dont remember it taking this long to harden up and dry. Maybe so Joined: Sep 26, Posts: 9, It sounds like you had too much water in the mix causing it to have low strength.

Sounds like possibly the water leached into the soil too quickly if you mixed it correctly. Do you have a very very sandy soil, or possibly a gopher hole the water would have drained to? If you mixed it correctly it should have set within 24 hrs max, with ultimate strengh in days for Quicrete. I have a very sandy soil, compounded by hidden gopher holes.
When I set the posts for my deck, I used the quick set version. I mean quick, within 30 minutes it was set. The soil here is clay. I dont know what the deal is.Mixing it in one of those plastic-tub wheelbarrows, the one you bought at the hardware store because they are cheaper, lighter, and the guy at the hardware store assured you they work just as well as steel wheelbarrows, unless you ever need to mix a batch of concrete.
First, buy a steel wheelbarrow. Farmers wanting to build new silos, understand. So I heard his talk many times, and adding too much water was his big admonishment. Too much water—even just a little too much—makes for weak concrete that will fail prematurely, particularly in regions where you have freezing temperatures in winter.
In all climates, too much water leads to flaking and easy chipping of concrete surfaces, such as a stoop or patio. Manufacturing Portland cement is an inexact science.
Get the inside of the wheelbarrow wet, add your concrete mix out of the bag, wear gloves, and create a wide, round crater in the middle of the dry mix. Add three-quarters of the recommended water, mix it up, and see what you get. If you are mixing only a few bags in the wheelbarrow, those big concrete hoes are not necessary. I use a straight edge shovel, works fine. Constantly scrape the straight edge along the bottom of the wheelbarrow to be sure you are turning over all the mix.
No more than a cup or so. Work it with your shovel again. Really work it, front to back, side to side. Need a bit more water? OK, but a very little bit, at the end of mixing a proper batch, the final amount I add might be a tiny splash with the hose. A standard bag with aggregate high content of small, round pebbles should have a little less slump than a mix that includes only sand, such as a patch or filler mix.
A good aggregate mix will perform as described in the photo. When you have it right, you will see a quarter-inch wide ring of very watery mix all around the perimeter of the wheelbarrow, everything else will have some texture to it. Don Engebretson The Renegade Gardener. Facebook Instagram.

Thread Starter. I just mix mine till I don't see any more dry crete. Then I'll add just a little bit more water to loosen it up a little more but not too much. Must let it cure for two days to be sure. I don't even mix it. Them I add water to the top. Let it set for a little while the water soaks in. The sackrete will set up. All that mixing is like work. Hope this is helpfull. I agree with Crappiefarmer, add just enough water until you don't see any more dry concrete then add just a little bit more.
I mix mine in a wheelbarrow then transfer it to my tubs or buckets. I believe,from past experiences, that you can add too much water while mixing. I like it to be well mixed but a little hard to stir around, not soupy. Another thing to watch out for is that you don't place your PVC or bamboo in a fashion that would make your concrete have weak areas in it.
I have had a few PVC beds that I made in shallow dish pans break apart on me when I tried to move them. Originally Posted by pappacrappie.

It takes a longer time to set when you have cool temps. You can look at the concrete and tell if its too green. Like Slabbandit stated leave enough space that it will be strong.
I also will drill a hole in the bottom of my PVC pipe to give the concrete something to grip on. I've pulled the pipe out of green concrete try to get them out of the mold.During these challenging times, we guarantee we will work tirelessly to support you.

Quikrete is a packaged concrete mix that can be used by homeowners and contractors alike in renovating, construction, and landscaping projects.
There are many different types of Quikerete products, but concrete and mortar are the most common. You can mix them either by hand or by using a mixing machine. To mix Quikrete concrete by hand, start by putting on a pair of safety goggles and some waterproof gloves. Next, put the desired amount of Quikrete mix into a wheelbarrow or mortar tub and make a hole in the middle. Then, add 3 quarts of water for every 80 pounds of Quikrete, and use a hoe to mix the water and concrete together.
When the concrete is ready, it should feel like wet oatmeal and hold its shape when you squeeze it. To learn how to mix quikrete with a machine, keep reading! Did this summary help you? Yes No. Log in Facebook Loading Google Loading Civic Loading No account yet?

I think I put too much water in the concrete Thread starter a Start date Aug 18, I got a bag of that ready mixed 'postcrete' - it said 'dig a hole, half fill with water then pour the mix in'.
Well, I think the hole might have been a bit wide so when I poured the concrete mix in it disappeard below the water level. This was on sunday afternoon, and within half an hour or so it had gone firm but not hard.
Right now, I can still stick my finger into it if I push hard enough. Will it eventually go off properly or have I buggered it up? There is enough room between the top of the concrete and the soil level to chuck another bag in with less water!

Michael McNeil. The Natural Philosopher.Many concrete projects will deplete your expense account -- you'll have to rent a heavy-duty concrete mixing truck and all the other materials you'll need. Then, if you can't get the truck right up to the site where you'll be laying the concrete, you'll need additional transportation equipment and labor. You'll usually have to hire a professional to do the job, adding yet another expense.
Taking care of your concrete needs with Quikrete might save you money, time and effort. The general rule for achieving a good Quikrete texture is to use one part water for every five parts of mix. For the best results, it should have the consistency of modeling clay [source: Quikrete ]. To get the right mix, you may need to experiment with the proportions, the way you would when trying to perfect your bowl of oatmeal.
If the Quikrete is too thick, add small amounts of water slowly. If it's too thin, add more Quikrete mix. When you've gotten the desired results, you can use a small garden shovel to do small touchups, or mold entire batches of Quikrete into large projects. Mixing Quikrete is easier than mixing concrete, but it can be challenge. To simplify this process, John Shoemaker invented the Cretesheet, which is basically a tough, square piece of tarp plastic about 4 feet square 1.
You place the Quikrete mix in the middle of the sheet, add the appropriate amount of water, and then you and a partner can simply move the handles up and down to mix the Quikrete.

Calcium chloride causes the concrete to harden, or set, within 30 minutes or less of adding water to the mix. It can then take up to 4 days to cure and harden to its maximum strength. Keeping quick-set concrete completely dry right up to the point of use is crucial to the successful mixing of the concrete, so it is not advisable to use it in the rain. While quick-set concrete is still in the bag, moisture can leak into it and cause it to clump.
Once it has clumped, it is ruined, as it cannot then be mixed correctly or thoroughly. It is important to stack it on pallets off the floor or ground whether indoors or out. If outdoors, the concrete bags must be stacked and tarped in such a way that water runs off and does not contact the bags, much like a roof is sloped to allow and direct the flow of water run-off. The proportions of mixing quick-set concrete must be followed carefully in order to get the right slump.
Slump is the term used to describe the consistency of the mix, and is determined by piling the mix up and measuring the height of the pile after it slumps, or settles. If mixed in the rain, it is difficult to determine how much rain is getting into the container while mixing; this can unbalance the proportions of materials, causing the concrete to weaken or not mix properly.
It is possible to pour small projects in the rain if your work area is protected from direct rain, and especially if you have a dry shelter adjacent to the project in which to handle and mix the concrete. If setting a post or footing or other small project, it may be possible to set up a quick shelter out of stakes and tarps to shelter the area. Winds, however, can make even this impossible, and a wet pouring area can negatively affect the curing process.
Keep in mind the water held by your own clothing, as well, as you handle dry bags of quick-set concrete. It is also possible to use quick-set concrete without mixing it, relying instead on the already-present moisture in the ground to sufficiently moisten the mix.
This works for setting posts. Dig the hole to three times the diameter of the post. Moisten the hole with a garden hose, if it's not raining.
Set and level the post using a level or plumb line, and pour the dry quick-set concrete around the post. Avoid standing water in the bottom of the hole -- too much water can cause the cement to weaken. Brace the post so it does not move while the concrete sets up.
