What is the best mix for concrete?
Warm water (for mixing) An accelerator admixture (calcium chloride) If you need a concrete mix that will set up fast, plan to use at least a 4000 psi mix. This type of mix has more cement than most of the regular concrete mix designs. More cement in the mix means more heat of hydration as the concrete sets up, speeding up the curing process.
What is Sakrete's 50 lb bag called?
You guessed it, Sakrete has a 50lb bag called "Fast Setting Concrete MIx". (I see a trend here)
What happens when cement and water mix?
Heat of hydration is a chemical reaction that takes place when cement and water get mixed together. If the water is COLD, there is less heat that develops and the concrete sets up slower. If the mix water is HOT, there is more heat that develops, which makes the concrete set up much faster.
How much water do you put in quick set concrete?
Depending on soil conditions, this will require about 1 gallon (3.8 L) of water per 50 lb (22.7 kg) bag.
Is fast setting concrete as strong as regular concrete?
Fast – setting concrete isn’ t just simple and fast, it’s also durable and strong, reaching 4000 psi — or pounds of force per square inch —after a month. That’s stronger than the concrete used for foundations on most homes.
How long does quick concrete take to dry?
The concrete sets up in 20 to 40 minutes, so you can quickly move on to the next stage of the project (a great convenience when setting fence posts) or backfill the hole to finish the job. Under normal curing conditions, you can apply heavy weight to the post (a basketball backboard, for example) after just 4 hours.
Is quikrete as good as concrete?
Quikrete premixed concrete is just as good, and strong, as traditional concrete you buy from a plant or concrete you mix on site. Concrete is made from sand, cement and aggregate stone and that’s exactly what’s in Quikrete premixed concrete. it’s very strong and sets much quicker than traditional concrete.

Will concrete set if it’s too wet?
When there is too much water in your concrete mix, however, it will have the opposite effect and the mix will be ‘swamped’, which will lower the rate that the chemical bonds form and therefore reduce the strength of the cured concrete.

Can I use quick set concrete in the rain?
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.
How does watery concrete affect the strength of concrete?
A watery mix actively reduces the compressive strength of the dried concrete. Usually, every additional inch of slump in the concrete reduces the compressive strength of the final product by roughly 500 psi. That strength degradation can add up quickly, and can be absolutely devastating depending on what it is you are trying to build.
Why is concrete so wet?
When a concrete mixture is too wet, it causes a greater amount of shrinkage during the drying process than is needed. As a result, the concrete has a great likelihood of cracking and for those cracks are likely to be a fairly good size.
What is the most common mistake made by concrete workers?
One of the most common mix mistakes made by the average concrete worker is adding too much water to concrete . Let’s take a closer look at why that is, and what happens when a concrete mix is too wet.
What is concrete made of?
Usually it’s a combination of water, cement and sand. As such, not every mix is created equally. That means that if something is wrong with your mix at the beginning, it could ruin the entire concrete project.

It can be frustrating to have to throw out an entire batch of concrete, or even worse, to have to send a fully-loaded mixer truck back, but the truth is that the mix is the most important part of a concrete product.
Does concrete have more water?
It’s also worth pointing out that concrete with a higher amount of water in it makes for a more porous final product. As a result, the way that concrete reflects light and holds something like a stain is drastically changed as a well.
Do you need to mix concrete more than once?
If you are working on a concrete project that requires more than one mix or load, it’s important to make sure that each batch of concrete is mixed the same way. If one batch is more watered down than the rest, it will be very clear on the finished product.
What to do if you add too much water to concrete?
Don’t panic if too much water is added during the mixing and it becomes too thin. Just add more concrete to the mix and keep mixing until there are no dry spots left inside the container. This is when a battery-drill and concrete mixing bit come in handy.
How to use fast setting concrete?
To use Fast-Setting Concrete, all you must do is add water to the pre-mix. This sounds simple, but often when being delivered to the store, the mix is exposed to the elements. If caught in the rain or humidity long enough, the concrete mix will absorb some of the moisture and begin hardening.
How to make concrete harden faster?
Hot water will make the mix harden significantly more quickly. When adding the water to the concrete pre-mix, take a tool and scoop out the middle creating a hole. Pour the water into the hole.
How to mix concrete with a spreader?
First add the concrete pre-mix into your bucket. Then take the mixing tool, whether it be a concrete spreader or a concrete mixing auger, and mix the dry pre-mix. This practice helps prevent large clumps from being an issue later.
What happens when you wash concrete?
Many people do not think about what happens to the concrete after you finish a project. It is common to find inexperienced users have washed it out in their sink or bathtub. DO NOT DO THIS. Washing out concrete into the plumbing of a house can cause expensive damages. Often the concrete will stick in the catch or to a pipe and begin accumulating other debris blocking up the pipes or septic system. The best solution is to wash out the bucket outside with a hose. It will leave a residue in the grass (or a chunk of concrete depending on how much you’ll be washing out. While that is not ideal it is better than damaging your house’s internal plumbing.
What to do when you first buy a concrete bag?
When you first buy and open a bag, you’ll want to check for any large chunks of hardened concrete. Not only will you not be able to use this bit, but it will also change how much space the concrete can cover. If there are any large chunks, bring it back to the store it was bought from and get it changed out for a new bag.
How to make concrete thicker?
Start Slow and Add Water a Bit at a Time. To get the concrete mix to a good consistency, add the cold water a little at a time. Doing so prevents the pre-mix from getting too thin or “soupy”. Ultimately, this type of concrete should be a thicker sludge consistency (chunky and thick) when done properly.
How to mix concrete with water?
Add Water. It is best to start with the minimum amount of water listed on the 60-pound bag of concrete's label. For hand-mixed concrete, add the water in all at once. If you use a concrete mixer, add half before you start the machine and the other half while the concrete is mixing. Mix the water in well.
What is packaged concrete?
Packaged concrete is a premixed combination of cement, sand and gravel. It is readily available at most home and garden centers and often sold in 60-pound bags. To prepare packaged concrete mix, all you have to do is add water. Determining the exact amount of water, however, is not such a simple process. Advertisement.
How to make sure you have enough water in concrete?
To make sure you have the right amount of water, make ridges in the mixed concrete. If the concrete is too thick to make ridges easily, the concrete needs more water. Add more water incrementally in small measured amounts. Mix each addition in thoroughly before adding more.
How to determine how much water to use for concrete?
For example, if you only need 30 pounds of concrete, that's one-half of the total amount. Multiply your minimum and maximum water amounts by one-half to determine the amount of water you will need.
