Hi, my name is Giulliano Prieto, a general engineering contractor with Prieto Engineering in Los Angeles, California, and today I will show you how to use a concrete mixer. The materials you will need are a wheelbarrow, a shove, a concrete mixer, concrete premix and water. A concrete mixer is a barrel with a machine at the back end of it that spins the barrel. What this does, is it enables us to mix several bags of concrete continuously throughout a project without using too much of hand labor. Now, the reason why is that it's very difficult to mix concrete by hand in a wheelbarrow all day long or throughout more than about three four bags of concrete. Now, I will demonstrate how to use a concrete mixer. The first thing that we will do is we will take our water and we will add about one gallon of water into the mixer. Make sure that you add enough water per the manufacturer's recommendations on a premixed bag of concrete. The next thing that I'm going to do is I'm going to take the bag of concrete, open it at the top and lift it into the barrel and pour the entire amount of the contents into the barrel. Now that the concrete has been placed in the mix with the water, we will now turn on the machine. Allow the concrete to mix long enough until all of the concrete, any dustiness is mixed very well with the water. Once the concrete mixer has turned several times, feel free to look into the mixer. If it is not quite to the consistency that you want it to, feel free to add a little bit of water to adjust it. Now that my concrete is to the right consistency that I need it at, I'm going to now tip the barrel into the wheelbarrow and take it to the appropriate location. Most of these concrete mixers not only tip, but they also turn to the appropriate location. My name is Guilliano Prieto with Prieto Engineering. Thanks for watching my video on how to use a concrete mixer. I've got a job to do. We'll see you next time.
