How to mix cement with an electric or petrol mixer
- Keep your bags of Portland cement in a dry area, up off the ground and covered with plastic to protect them from rain and ground moisture.
- Start the loading of the mixer by using a garden hose on the inside of the mixer drum. It doesn’t take a lot of water to do this. This also works best for keeping the machine clean during and after use.
- Add water to your mixture using a bucket so that you can keep track of the amount used and duplicate it more easily on following loads.
- Use this simple, time-tested formula for a common concrete mix ‘ 1:2:3 parts by dry volume. That is: one part Portland cement, two parts sand and three parts heavy aggregate. Masonry mix, of course, has no heavy aggregate and uses a better quality of fine sand or plastering in its mixture.
- Make small additions of water to your first few batches of concrete until you learn what consistency you will achieve with the different amounts of water. In general, a consistency of a very thick cake batter is the desired result. Such a mixture will be workable when wet and strong when dry.
- Mix only the amount that you can use in a short period of time. Once the cement-and-water chemical reaction starts, you have only a limited amount of time to work with the concrete.
When you are finished using the mixer , make sure to wash it out with a garden hose straight after use.
