Fence Post Concrete Mix Ratio

3000 psi concrete mix ratio.

Fence post concrete mix ratio.

I ve easily used over 300 bags of this stuff throughout the years in my business. Depending on the application concrete mix design can be complex. Its cheaper than the other stuff and easier to move than the 80lb bags. Concrete is always best mixed using a cement mixer to ensure it s even but if you only need to mix a little hand mixing is ok see mixing concrete project above for tips on how to do this.

So six foot high fence posts ideally need to be buried three feet into the ground. Some additional things to consider when finding a suitable mix design include but are in no way limited to the following. I have an 8 auger so i average 2 bags. The general rule of thumb when setting a post is that the depth of the post s hole needs to be 1 3 to 1 2 of the actual above ground height of the post.

In terms of the ratio to use for a concreting fence posts the best mix is a mix of 1 2 4 1 cement 2 sand 4 aggregate. The below table gives a basic indication of the mix ratios used for different purposes but should be used as a guide only. 517 pounds of cement or 234kg 1560 pounds of sand or 707kg 1600 pounds of stone or 725kg. As a quick answer a concrete mix ratio of 1 part cement 2 parts fine aggregate sand and 4 parts course aggregate will cover most general domestic jobs.

By measuring the cement stone and sand you will have a consistent concrete mix throughout your entire project.
