Mixing concrete, whether by hand or using a machine, is hard work. It can also be very dangerous if you don’t take the proper precautions. In this post we are going to explore the best ways to mix concrete and some safety tips that you should review before starting any concrete project.
1. Always wear safety glasses and gloves when mixing concrete.
2. Use a dust mask when mixing dry concrete materials such as cement, sand, and stone dust.
3. Mix dry material for a few minutes before adding water until all the dry material is wetted out and then add the remaining water to achieve the desired consistency of your mix.
4. Turn off all power tools before adding water to the mixer or wheelbarrow; never add water to a running mixer or wheelbarrow with a running motor or paddle.
5. Use eye protection when pouring in water from a hose or watering can.
6. For most small jobs around the home, you will not need more than about 1 cubic yard of prepared concrete, which will fill up about 12 standard wheelbarrows (a little over 1/2 cubic yards each).
Most people don’t realise that mixing concrete is one of the most difficult things to do, but we’re here to make it easier.
Whether you are doing some DIY or getting someone in to do a professional job, these seven tips will help you to get your concrete mixed and poured just right.
1. Don’t Mix Concrete Too Early
Many people make the mistake of mixing their concrete too early, only to find that it starts setting before they can use it. What they should have done is mixed the concrete and then poured it into a wheelbarrow so that they can transport it quickly and easily. You can also use a mortar tub which is exactly the same as a wheelbarrow, but designed for smaller jobs.
2. Know How Much Concrete You Need
If you know how much concrete you need then you’ll be able to mix the correct amount of material in one go. To work out how much you need, check out our concrete calculator and enter the length, width and depth of your job into the three boxes on the left hand side. The calculator will tell you how much concrete you need in cubic metres and cubic yards.
Mixing concrete is a basic skill that all DIY enthusiasts should know how to do. It is vital for many home improvement projects, from building a small garden wall to constructing the base for a shed.
However, it can be quite tricky to master. If you get the mix wrong, your concrete might set too quickly or not at all. Or you may find that it cracks or crumbles away in places.
We are going to look at how you can mix concrete successfully so that it sets properly and lasts for years to come. We will also give you some safety tips to ensure that the process goes smoothly and doesn’t cause any accidents.
Concrete is a mixture of fine and coarse aggregate, cementitious material (usually Portland cement), and water. The mixing of concrete components is done with a mechanical mixer. The two types of concrete mixers are:
Batch – For small jobs that require less than three cubic yards, a batch concrete mixer will be used. A batch concrete mixer consists of a revolving drum that holds the ingredients in its interior. Some modern batch mixers can produce over three cubic yards of concrete per hour.
Drum – Very large concrete projects require mixers with an output capacity of six to nine cubic yards. Because these machines are so large, the mixing drum rotates on a pivot to make it easier to pour the finished product where it’s needed.
Mixing Concrete Tips
There are many reasons why a person might want to mix concrete for one reason or another. Perhaps it is to use as part of a home improvement project, or maybe it is to make a strong and sturdy post for a garden fence. Whatever the reason, there are some tips that will help you achieve perfection when mixing concrete.
For small jobs, such as setting posts, you can buy bags of pre-mixed concrete. All you have to do is add water and mix well. However, if you are planning on pouring a slab or doing other larger jobs, the best option is to mix your own using Portland cement, sand, gravel and water. There are three ways in which concrete can be mixed: hand mixing, using a cement mixer and using ready-mix concrete that just needs water added.
For most jobs around the home though it is unlikely that you will need more than about 2 cubic yards of concrete at any one time. This amount of concrete would require 1 bag (94 pounds or 42.64kg) of cement plus 2 cubic feet (0.0574m3) of sand plus 4 cubic feet (0.1142m3) of gravel along with around 2 gallons (7.57 liters) of water to make about 0.
There are many ways to mix concrete, but for most jobs you want to know how to mix concrete in a wheelbarrow. It can be used for small and large jobs, and it’s easy to clean up.
For mixing concrete in a wheelbarrow, first load the dry ingredients into the wheelbarrow. Then, add water on top of the dry ingredients. Use a shovel or hoe to mix the two together. Use a circular motion to mix the two together and break up any clumps of dry material. Once the ingredients are mixed together, use the shovel or hoe to scrape the concrete from the sides of the wheelbarrow down into the center. Continue doing this until everything is mixed together.

Most of us have mixed concrete at one time or another. It is not a difficult job, but you should take a few precautions to ensure success.
Preparation
First, make sure your formwork is well braced and ready for the concrete. You do not want it to move when you are pouring the concrete. Next, you need to determine how much concrete you will be using. You can do this by filling your formwork with water and then draining it into a bucket multiple times until your bucket has the right volume of water. Each time you drain the formwork into the bucket, multiply that number by 7.5 to get the approximate volume in cubic feet of concrete required. For example: If I filled my formwork 3 times with water and used 8 buckets each time to catch the water, my total volume would be: (3 x 8) x 7.5 = 180 cubic feet of concrete needed.
You also need to determine how many bags of cement will be required. There are several online calculators available that will help you figure out how many bags of cement will be needed for your project. One such calculator is here: [http://www.](http://www.)[concrete](http://www.)[calculator](
