QUIKRETE® Fast-Setting Concrete Mix (No. 1004) is a special blend of fast-setting cements, sand and gravel designed to set hard in approx. 20 to 40 minutes. Sets posts without mixing. Pour dry mix into hole and soak with water.
What is the quick setting cement?
Quick-Setting Cement is a very fast setting concrete repair product. This product has the unique characteristic of being able to be sculpted and molded as it sets. The set time for this product is 10-15 minutes. Quikrete 10 lb. Quick-Setting Cement is perfect for making repairs to the edges of curbs and concrete steps.
How do you cement a post in the ground?
- Dig the post hole, making it three times the width of the post and at a depth equal to 1/3 to 1⁄2 of the above-ground length of the post, plus 6" (right).
- Pour 6" of gravel or crushed stone into the bottom of the hole.
- Set the post in the hole.
Quikrete's Concrete Mix yield's about .15 cubic feet for every 20 pounds of mix, so a 40-pound bag yields .30 cubic feet, 60 pounds of concrete mix yields .45 cubic feet and an 80-pound bag yields .60 cubic feet. One 50-pound bag of Quikrete Fast Setting Concrete Mix yields about .375 cubic feet.
If the rain occurs when the concrete is fresh (about 2-4 hours after mixing), the surface should be protected from the rain. If the finishing process was recently completed, rainwater may not cause damage as long as it is not worked into the surface and the slab is left untouched.
Curing Time for Concrete. In standard industrial cases, full strength concrete is recognized at 28 days. At seven days, you should have concrete that is cured to 70% full strength or greater. But to answer the question of, “How long does concrete take to set?”, concrete setting time is generally 24 to 48 hours.
A 80 lb. bag provides 0.6 cubic feet of cured concrete. If you have concrete delivered it is sold by the yard (which is a cubic yard = 27 cubic feet).
There are 27 cubic feet in a cubic yard. Dividing 27 cubic feet by the volume of the bag will give you the number of bags you need. An 80# bag of Sacrete yields 0.6 cf of concrete.
27 cf / 0.6 cf = 45 bags per cubic yard.
27 cf / 0.6 cf = 45 bags per cubic yard.
It has a walk-on time of 10 - 12 hours. QUIKRETE® 5000 can be used for any application requiring concrete in a minimum thickness of 2" (51 mm), such as slabs, footings, steps, columns, walls and patios. YIELD.
Quick-Setting Cement sets in about 10 minutes so do not mix more than can be used in 10 minutes. Mix Quick-Setting Cement to the consistency of modeling clay. Start with about 1 part water to 5 parts of Quick-Setting Cement. Mix thoroughly.
Effects. When fast-setting concrete mix is used, setting takes place in 20 to 40 minutes. Typically, you can apply some weight to the posts after 4 hours, but it's a good idea to wait at least 24 hours before resuming fence construction.
Water cure:The concrete is flooded, ponded, or mist sprayed. This is the most effective curing method for preventing mix water evaporation. Make sure you allow proper time for water curing. Water retaining methods:Use coverings such as sand, canvas, burlap, or straw that are kept continuously wet.
Sakrete Fast-Setting Concrete Mix will set in approximately 30 minutes. Standard concrete mixes such as Sakrete High Strength Concrete Mix and Maximizer Concrete Mix can also be used to set posts and poles but requires the material to be premixed prior to application.
Empty the mix into a mortar tub or wheelbarrow and form a depression in the middle of the mix. Measure the recommended water amount (each 80-pound bag of concrete mix will require about 3 quarts of water). Pour approximately 2/3 of the water into the depression. If using liquid cement color, add to the mixing water.
Rapid Hardening Portland Cement (RHPC) is a special purpose cement used in concrete to achieve a higher rate of early strength development, compared to using Normal Cement. The improved early performance of RHPC is achieved principally through increased product fineness.
Dig post hole so diameter of the hole is 3 times the width of the post (i.e., the hole for a 4” wood post should be about 12 inches wide). The depth of the hole should be 1/3-1/2 the post height above ground (i.e., a 6-foot tall fence would require a hole depth of at least 2 feet).
The most often used admixtures are air-entraining agents, water reducers, water-reducing retarders and accelerators. Admixtures are used to give special properties to fresh or hardened concrete. Admixtures may enhance the durability, workability or strength characteristics of a given concrete mixture.
For each 80 lb (36.3 kg) bag of QUIKRETE® Concrete Mix to be mixed, add approximately 6 pt (2.8 L) of fresh water to the mixer. Turn on the mixer and begin adding the concrete to the mixer. If the material becomes too difficult to mix, add additional water until a workable mix is obtained.
If you need to mix concrete by hand, there are two options: It has all the ingredients dry mixed together for making concrete, i.e. the cement, sand and stone. All you have to do is put it into a bucket, wheelbarrow or on a piece of plastic on the ground, add water and spend a few minutes mixing it.
Remember, the depth of the post hole should be one-half of the above-ground post height. (Example: For a 6 feet above ground post, use a post with an overall height of 9 feet and place 3 feet in the ground). The calculator will indicate the number of 50 lb. bags of QUIKRETE® Fast-Setting Concrete you need.

Thermal and sound insulation- The air present in the hollow area of these bricks make them thermal insulators. They keep the interiors cool in summer and warm in winter especially the 'clay hollow bricks'. They also provide more sound insulation as compared to solid bricks.
What happens when you add too much water to concrete and/or other cement mixes? Over-watered concrete may lead to lower strength, reduced durability, shrinkage cracking, and a variety of surface problems. It is critical that the proper amount of water be added to concrete and other cement mixes.
