What is quick dry cement?
Fast-Setting Concrete Mix is a special blend of fast-setting cements, sand and gravel. Designed to set hard in 20-40 minutes. Sets posts without mixing. Used to set mailbox posts, fence posts and lamp posts without mixing. Pour dry mix into hole and soak with water.
Pour up to one gallon of water into the hole until is soaks into the QUIKRETE Fast Setting Concrete Mix and allow the concrete to set for 20 to 40 minutes. Wait four hours before placing any heavy objects or allowing traffic.
- 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.
- 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.
- 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.
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.
- 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.
- How Long Does It Take? The concrete patio slab will take five to seven days to cure. During this period, the slab must be kept wet at all times with garden sprinklers or a garden hose. It must never allow it to dry out all the way during the curing period.
- This means the “density” of concrete is about 145 lbs per cubic foot. Now that we have that information we can calculate the yield. Add up both the dry material in the bag (80 lbs) and the water it takes to mix it up (1 gallon which weighs 8.3 lbs) for a total weight of 88.3 lbs.
