Welcome back to Albany County Fasteners, Fasteners 101. I'm Bob and today I'm
going to show you how to mix some concrete. But before we do that, please
subscribe, like, and share my videos and hit the bell so you get new content
warnings. Let's get started.
This is a bag of concrete - 50 pounds.
It's quick-setting concrete. This is what I selected. They have quick-setting, they have
slow setting, you know, many different mixtures. You can find it at your home
improvement store. This is by quikrete. I did many years of concrete work and
many would think that, you know, "it's a bag of concrete; it's pre-mixed." Well there are some
important things that you need to know. Especially with fast setting concrete.
Fast-setting concrete sets very quickly, so you have to have your materials ready
before you mix the concrete. I'm going to show you how to properly mix the concrete.
So I poured some of this fast setting concrete into this bucket.
It's a 5 gallon bucket I guess. You get these at Lowe's or Home Depot,
any of those. One good thing to do before you put any water in is to make sure
you mix the materials around after you pour it out of the bag.
That makes sure that all the materials are nice and loose. Now a couple of tips:
If you go to your box store and you buy a bag of this product and you come back and you have
chunks or it's not fine, bring it back, get a new bag. Sometimes when they
ship these products they're out exposed to the elements; they could get hit with
water, and then the product starts to set up which is no good.
So I would highly recommend that you make sure that you have fine product.
Now I'm gonna go get some water and we're gonna start to mix the product.
So I went and got my water. This is cold clean tap water.
Do not use hot water. Hot water will set the concrete faster, so you want to avoid doing that.
It's a good thing to just pull out of the center here,
and pull to the side some of the concrete and basically just dig a
little hole there to pour the water in.
I'm going to start to pour this in then I'm gonna mix it.
You want to go a little bit at a time, not too much, because then it'll become too soupy and then you'll
have to put some more concrete in, which I might have to do here but I'm just
gonna keep mixing it. I'll probably need more than what I have here anyway.
To do this little project I'm doing.
You just keep mixing it. Make sure you get the bottoms and the sides.
Because otherwise you're gonna have dry pockets with dry concrete. You got to
make sure you mix it well. Now I'm using this ladle, you can also get a battery
drill and put a concrete auger on it and mix it that way. For this I'm just
doing it by hand. Make sure you get down to the bottom. You get everything mixed well.
I'm almost down there now. Now you don't want it soupy like it is here.
So I'm going to add some more concrete to this but you want to make sure that it's well mixed.
You're better off when you have fast-setting concrete that it's a
little more wet because the drier the faster it's going to set up on you.
I'm all the way down to the bottom now. Now it's coming together well.
Okay I'm going to add some more concrete.
I like to start off more soupy than dry because it makes it easy to get everything that's on the bottom.
If you're working on your project and as
you get to the bottom and find the concrete is setting up, because this
is fast set, do not add water to loosen up the product. Throw it out.
Start off with a new batch, even if it's a little bit. Just make sure you put a little bit in
there with very little water, sometimes with cups of your hand or a little cup.
Pour the water in as you mix it so you can finish your project off. It's a little tip.
Always a little bit at a time. Don't go too fast because if you put
too much in then it's going to get very dry very quickly and then you have to put
more water in. This is getting perfect now. Now this is a small batch. You can
get a big tub with a hoe and you can mix it.
Break your bags open and put it into a big bin. We're almost there. This is getting to
the perfect consistency that I want. This is also fast setting.
So fast setting, once it starts to get to that consistency, will start to set up pretty quickly.
Just a little bit more.
Not much...I think this is gonna do it. Yep. Now you can see it. That's what I'm looking for.
Okay. I don't see any dry material.
You want to make sure you have nothing dry. You want to make sure it's thoroughly
mixed and always wear protection. You need gloves. You should have a mask on,
so you don't inhale this stuff. It's not the greatest stuff for you.
Concrete has lime in it. You need to protect your skin from it because if you
use it many, many times, it also can do some damage to your skin.
They don't tell you that typically but you learn that over the years.
So here we are. Looks good. Just found a dry spot there.
But I think I'm good for my little project. That's the perfect consistency that I want.
It's not too watery but it is nice and chunky and thick.
This will set up pretty quickly once I put it into the product that I'm trying to
develop here for my next video.
A piece of concrete that is already setting up and then you pour a fresh
batch on top of that, they call that a cold joint. That's where you're going to
have a possible break and you will see a joint in the concrete.
So you kinda wanna-when you're working with concrete-you want to move fairly quickly.
Especially fast setting. Slow setting, normal setting, you know it's much
more easier to work with. I would highly recommend that, if you
haven't worked with concrete before. if you have a bag and you have extra
material, it's good to roll this up, take it, put it in a plastic bag like so.
Seal it up tight. Make sure you don't have any holes in the bag because once you break
that paper bag open moisture in your garage or your basement will start to
penetrate the concrete and then when you go to use it let's just say two months
three months, this will prolong the life. If it's over a year old chances are that
you'll come back to this and it will be chunky. You just need to throw it out at that point.
A final tip: cleaning. Do not clean concrete buckets out in your slop
sink, your toilet, your regular sink in your house, your bathtub, don't do it.
Clean it outside. Get a hose, clean the concrete out in your grass somewhere
that you just don't want to see it. Though it will leave a residue around.
If you clean it out in your sink, slop sink, toilet, or your bathtub,
the trap in the plumbing will collect the concrete sand and it will set up in
there and the end result is it will reduce the amount of flow of water and
whatever else is in there by a substantial amount.
Thus clogging your sink eventually. Hair will cling to it.
A lot of people do this. It's a big mistake. Don't do it.
That's how you mix a bag of concrete. I probably used about 75% of this bag.
Thanks for watching. Leave me some comments. Give me your thoughts.
I can pour it if I want to but it's just easy for me-
It's on here, it's not gonna come out.
