In this cement mixers guide, we’ll discuss what you need to be looking for when choosing the right cement mixers for the job.


With a range of cement mixers on the market, the level of choice can be overwhelming and confusing. However, knowing the basic features and benefits of the different cement mixers on offer will help you make an informed decision.


Cement mixers are a significant investment, and matching your cement mixers with the type of project that you’ll be undertaking will be essential.


This cement mixers guide will talk you through the various options available highlighting the types of uses they are best suited to.




This guide will also talk you through the fundamental processes involved in mixing concrete, as well as all of the related processes that surround using cement mixers. This will help you to make an informed decision about the type of cement mixers that you’ll need.


Mixing Concrete With Cement Mixers


The secret to creating successful concrete is finding the right mix. Successful concrete is anything that is fit for purpose and will stand up to changes in the weather, and maintain the integrity of any structure that it homes.


Creating the right mixture is quite simple, as long as you understand the process. While you can mix cement by hand, it is far easier to make use of cement mixers as it will far less



You will need to mix your concrete to the right ratios. The ration that you use will depend on the type of job that you are carrying out.


The higher the ratio of concrete compared with sand and stone, the stronger the cement will be.


Using Cement Mixers to Create a Large Batch 15 Mpa Mix


For a low strength mix that is suitable for freestanding retaining walls, boundary walls, and foundations that are not reinforced, you will need a 15Mpa mix.

You will need one 50 kg bag of cement, two wheelbarrows of river sand, and two wheelbarrows of stone.


Using Cement Mixers to Create a Large Batch 25 Mpa Mix


A 25 Mpa concrete is a medium-strength mix that is suitable for light-duty flooring in homes, pathways, driveways, steps, patio slabs, light-duty house floors, garage floors and reinforced foundations.


It can be made up using 50 kgs of cement, one and a half wheelbarrows of river sand, and one and a half wheelbarrows of stone.


Using Cement Mixers to Create a Large Batch 30 Mpa Mix


For a higher-strength concrete, that can be used for flagstones, heavy-duty flooring, suspended and reinforced floors, suspended structural beams, and pre-cast beams, you will need a 30 Mpa mix.


You will need 50 kgs of cement, one wheelbarrow of river sand, and one wheelbarrow of stone.


Creating Small Batches

For projects requiring less cement, you can make up small batches. You can use any container such as a bucket to measure the elements of the mixture. However, you must use the same sized container for each part so that the ratios are correct.


For a low- strength 15 Mpa mix, use a ratio of one container full of cement, three and a half containers of river sand, and three and a half of stone.


For a medium-strength 25 Mpa mix, use a ratio of one container of cement, two and a half containers of river sand, and two and half of stone.


For the higher-strength 30 Mpa mix, you can use one container of cement, one and three-quarters of river sand, and one and three-quarters of stone.


Using Cement Mixers to Create a Perfect Batch


Once you have measured your ratios, you will be ready to put it into your cement mixers. Once mixed, you will be able to transfer it into your wheelbarrows and start to place it before it is compacted down.


Be careful about moving your mixed concrete. If you disturb the mixture too much when you are transferring it to your wheelbarrows the stone may settle towards the bottom.


You will need to work quickly once you have started to mix your cement. The time between mixing your cement and laying and compacting it should be less than 45 minutes.


If you are unable to place your cement within this time, you will need to cover your batch over to protect it from the elements.


If you do need to leave your cement for any length of time before you lay it, you should check that the consistency is still correct. If you’re unable to bring the cement back to life by turning it over with a shovel a few times, you will need to start again and create new cement.


Selecting the Right Cement Mixers for Your Project


If you are buying cement mixtures, it is essential that you buy the right type to match the use that you will get from it.


Decide whether you will be using your cement mixers for light or occasional use, or whether you need heavy-duty cement mixers for regular use.


Cement Mixers for Light Use


For smaller occasional masonry projects, you should look at electric cement mixers that have a capacity of 120 litres.


Often, the price difference between 60-litre drums and 120 litres is insignificant, so for the smallest projects, the 120 will at least give you more space than you will need should you end up carrying out projects that require more cement.


These types of cement mixers are lightweight and will be easy to transport.


Of course, as this type of mixer is powered by electric, you will need to use this on a site that has access to mains power, or a generator.


Cement Mixers for Heavy Use


If you are looking for cement mixers that will be used on a daily basis, that provide the flexibility for bigger batches, and that can be used on remote sites where access to power is limited, then you will need to get petrol-powered cement mixers.


These cement mixers will come with drums with a 360 Kg or even a 500 kg capacity.


Engine-powered cement mixers will require some maintenance to keep them running in good condition. You may even choose cement mixers that have Honda engines to provide that extra degree of quality.


Because of the size and weight of these types of cement mixers, you’ll need to think about transportation.


You could either opt to transport your cement mixtures on the back of a large flatbed van or trailer. However, another option that may be useful would be to choose cement mixers that have tow bars so that they can be attached to the rear of your vehicles.


What are the Elements of Cement Mixers?


If you are buying cement mixers, you’ll need to know a little about the various elements that they are made up from.


Cement mixers will have the following elements:


● A drum, inside which there will be mixing paddles

● A ring gear which goes around the middle of the outside of the drum

● The crack wheel which will help you tip your cement mixers to load and unload mixes ● A foot pedal locking system to keep the drum in place

● An engine or motor to drive the cement mixers

● A power cord, or fuel tank.

● Control switches to turn the cement mixers on or off.


What are the Benefits of Electric Cement Mixers?


One popular option for cement mixers is to have an electric powered motor to mix the concrete.


The advantages of these cement mixers are that they are low-maintenance. Not only will you save money on having your cement mixers maintained, but electric cement mixers are also often cheaper to buy in the first place.


Because you don’t need to buy oil or petrol for your cement mixers, they are cheaper to run. They will also always start immediately.


Because electric cement mixers tend to be lightweight, it makes it easier to move on the job. If you need to get your cement mixers upstairs, then an electric model may be the way to go.


The downsides to electric cement mixers are that they will generally only come with smaller drums; this makes them less ideal for larger jobs. They are also reliant on a power supply.


What are the Benefits of Petrol-Powered Cement Mixers?


Without the need for mains power, petrol-powered cement mixers can be used anywhere.


The more powerful engines on petrol-powered cement mixers mean that they are capable of creating bigger, heavier batches of concrete. Because of this, they will have larger drums. This makes them ideal for bigger jobs.


Of course, because they have petrol engines, these cement mixers will need servicing from time-to-time. You will also need to buy and carry fuel to keep your cement mixers going when they are on site.


Choosing the Right Cement Mixers for Your Needs


In summary, it is essential that you match the needs of your project with your choice of cement mixers.


Knowing how much cement you need, and the strength and ratio of the mix will help determine the size and power source of the cement mixers you choose to use.
