A 60 lb. bag of QUIKRETE Concrete Mix yields approximately 0.45 cubic feet of concrete. A circular area having a 21 foot diameter (10.5 foot radius) is 346 square feet. To cover with 0.25 feet (3 inches) of concrete will require approximately 86.5 cubic feet, or approximately 192 60 lb bags of concrete. Note that a standard slab is 4 inches thick, which would require approximately 118 cubic feet, or approximately 262 60 lb bags of Concrete Mix. Yields are approximate, and will be affected by waste, uneven sub-grade, etc.

You've got 86 cubic feet x 135lb of concrete per cubic foot = 11,683lb

11,683lb divided by 60lb per bag nets 194 bags. I hope you have help.

Your question is very vague. You can pour concrete on top of particle board, but why?

If it is a form, make sure it is properly supported. If you are making a concrete kitchen counter top, I recommend a book on concrete kitchen counter tops, You will have to search for it, but it has some very good information about pouring your own. Hope this helped.

QUIKRETE Concrete Mix may be applied over plywood if a metal lath is first installed to allow a mechanical bond to form, as the Concrete Mix could not bond directly to the plywood. QUIKRETE Concrete Mix should NOT be applied over particle board as the particle board may swell, deform, and lose strength if exposed to high levels of moisture. Concrete will also not form a bond with particle board. Depending upon the ultimate surface you wish to have for the counter top, installation of a cementitious backerboard over the particle board may allow greater flexibility in regards to the final surface you can apply. Note that it is not advisable to drive nails or screws into particle board, as they can provide an inlet for moisture, and / or cause the particle board to lose its shape when indentations are made on its surface. The use of QUIKRETE Polyurethane Construction Adhesive to adhere cementitious backerboard to the particleboard may be an option. You may wish to obtain further technical support directly from QUIKRETE at 1-800-282-5828.

If the question is "Can I use particle board as a temporary form for concrete" the answer is yes.

If the question is "Can I pour this type of concrete on top of particle board" the answer is no.

There is a lot of moisture in the concrete mix and if it is under the concrete the moisture and the weight of the concrete could weaken the particle board to the point of failure.

Using the particleboard a temporary form for curves etc can work if it is properly braced.

When placing fence posts, the depth of the post hole should be one-half of the above-ground post height, for example: For a 4' above ground post, use a post with an overall height of 6 feet and place 2 feet (24”) in the ground. For holes that are 24” deep, with a 12” diameter, and a 4” x 4” square post placed within, a single hole would require approximately three 60# bags of mixed QUIKRETE Concrete Mix. 8 posts will require approximately 24 bags. These are estimates and will vary based upon waste, uneven subgrade, etc. Note that the QUIKRETE Concrete Mix must be blended with water before being added to the hole.

If you're setting 4x4 posts, you're gonna want to dig your holes deeper than 1 foot. The Quikrete folks will tell you to dig a hole half as deep as the height of your post out of the ground. (e.g., for a 6 foot high post you would need a 9 foot long 4x4 with 3 feet of it being buried in the hole). While that will certainly be sturdy, I would go with 8 foot posts and bury them in 2 foot holes. Having said that, a 60lb. bag would do one hole and then some - maybe 3 bags for 4 holes - assuming the holes are about 9-10 inches in diameter. The Quikrete website has a good quantity calculator on it. Good luck.

That would be 8 cubic feet. From what I see Portland cement weighs about 145l/ft3. I would verify that number as it varies due to mixture aggregate, dry and chemical mixtures and the like. The density is variable due to the amount of water and air trapped inside. This is by design. I would say you need ABOUT 19 60# bags. 19.3 using 145lbs as reference.

Each bag is approximately .5 Cubic Feet

The math goes

14 feet X 14 feet = 196 square feet

196 square feet / 3 = 66 cubic feet (Note: Divide by 3 accounts for the 4 inch thickness)

66 cubic feet * 2 bags/ cubic foot = 132 bags

132 Bags - Note I did not account for the fire pit and I would recommend that you don't either. This gives you a few extra bags to allow for errors (dropped bags, uneven base, stuff on your shoes and clothing) and any left overs you can take back to the nice folks at Home Depot.

QUIKRETE Concrete Mix is a standard setting concrete, so it will have a typical set time of approximately 4 to 6 hours if the temperature is approximately 70 degrees F. At higher temperatures, the set time will be somewhat faster, while at cooler temperatures, it will be slower. Since the QUIKRETE Concrete Mix should have achieved its set prior to it being rained on approximately 12 hours after being placed, no detrimental results from the rain are anticipated – check to see that the material is hard to the touch, and the post is firm.

Multiply the number of cubic feet by 135lb to get the weight of the concrete, and divide by the pounds in each bag.

For your pour, use the area of a circle, pi times the radius squared.

3.14 x 22" x 22" x 12" deep is 18237 cubic inches.

18237 divided by 1728 is 10.55 cubic feet,

If you buy 60lb bags of concrete, you will need a bit more than 6.

You could always stuff some more rocks in the wet concrete so you don't have to buy a full bag.

The area of a circle is Pi times r squared, so 3.14 times 5 squared or 3.14 times 25 = 78.5 square inches.

Multiply the area by the height (60 inches). 78.5 X 60 = 4710 cubic inches.

There are 1728 cubic inches in a cubic foot. Divide 4710 by 1728 and we have 2.73 cubic feet.

I use 0.45 cubic feet per bag to calculate necessary volume. I suspect that the 60 pound bag was intended to approximate a half cubic foot, but 0.45 cubic feet is more conservative and works out in practice. So: 2.73 cu. ft. divided by 0.45 = 6.06 bags. 6 bags should be OK if you are careful. Be sure to vibrate or tamp and reinforce properly.

Volume would be Pi rsquared x h...radius is 5" or .42 ft...

So, volume would be 2.75 cuft...@ .45 cu ft/bag that would be about 6 bags (if my hs geometry memory is still valid...)

It can if you are looking for a rocky appearance for the finished product. I saw that Home Depot was carrying a fiber reinforced mortar mix that might work better. While it says you can do away with rebar, for something like a concrete bench the more support the better.

Yes, just remember to mix it up very well and when you pour it into the mold and to mix it more to get the smoth edges. No need to buy any special tools, a short 2x4 can be used to smoth it out. Buy a cheap garden tool to mix it up with.

Yes, QUIKRETE Concrete Mix may be used for creating a concrete bench. Be sure to follow the water content recommendations - Utilizing too much water could also cause excess shrinkage, which could lead to hairline shrinkage cracks as it cures. Depending upon the environment in which you live, you may consider using QUIKRETE Crack Resistant Concrete Mix, which contains fibers and air entrainment for increased durability in freeze / thaw environments. The designs you are considering will suggest reinforcing stainless steel for any portion of concrete which spans vertical supports.

Yes, it can be used to pour into molds. Be careful to keep the mix stiff and either vibrate it into place or use a thin rod to thoroughly agitate the material as it is placed in the mold. You probably will still have voids when pulled from the mold. Reserve a little bit of the fines (no stones), make a paste and rub it into the voids of the partially cured cast. Next day is usually OK.

Works out to about 16.5 Cubic Feet. Each 60 lb bag is .45 Cubic Feet so you would need about 37 bags. Note add a few extra bags just in case the bottom is not pefect, an oops what ever. You can take the ones you don't use back but you will screw up your project if you run out before you are done.

July 26, 2013

A 60 lb bag of QUIKRETE Concrete Mix yields approximately 0.45 cubic feet. An area of 66 square feet will require ~ 16.5 cubic feet or approximately 37 60 lb bags of concrete for a 3” layer of concrete. Note that standard slabs are 4” thick, which would require ~22 cubic feet or approximately 49 60 lb bags of concrete. These are estimates and will vary based upon waste, uneven sub-grade, etc.

Here's how to calculate the amount of concrete to purchase.

A cubic foot of concrete weighs 135 lb.

3" is 1/4 of a foot. 66 times 1/4 = 16.5 cubic feet.

16,5 cubic feet times 135 lb per cubic feet equals 2228 lb total.

Divide the total weight by the amount in the bag you plan to purchase.

Always buy a few extra bags as it is not good to run out, and Home Depot will gladly accept any you bring back.

At the end of the tpouring day, put a plastic drop cloth on it and weigh down the edges so the wind cannot blow under the plastic. This will keep the concrete moist. Leave it on for a week.
