How To Mix Concrete

Back By Popular Demand! We have many concerns about this topic that we believed we must re-invigorate our article about it and repost it for your 2013 tasks.

Concrete is a mix of cement, sand, gravel and water. Variations in the ratio of the components produces a mix suitable for different jobs however we will be advising you on a basic function mix ideal for most garden tasks and shallow structures not home structures.

Mix 1 part cement, 2 parts sand and 4 parts of gravel. What you used to measure the parts depends on just how much concrete you need– normally pails are the best step, one part being a level pail full. Including water is not a simple matter as the sand you are using might currently be wet. Use trial and error, add some water and mix up until the consistency is. How do you know – well a shovel complete will remain in a loose stack and not slop over the edges however the mix is soft enough for you to smooth and shape quickly.

What ever you are using the concrete to should be wet as this helps the concrete bind to it.

The mix dries and solidifies – however if it the conditions are too hot the mixture will dry unevenly and crack. If the concrete is in full sun on a hot day cover it will some shade – plastic or a sheet, to slow down the drying.

As the mix dries, it will solidify. However the drying, or ‘curing’ ought to be gradual, otherwise breaking may take place. To prevent splitting, plastic is put over the curing concrete to trap the water inside, ensuring steady curing.”

If you are blending a lot of concrete it pays to rent a cement mixer as it is back breaking work. Getting an even mix is really crucial for producing strong concrete.

Concrete contains cement plus sand and gravel. So do not make the mistake of purchasing bags of cement and simply blending with water – the mix will not be strong and might simply powder when dry.
