Hello,

I bought a few 94-lb bags of portland cement. I read that these are 1 cubic feet each.

I also bought loose sand and gravel to make concrete.

How many 5 gallon buckets of sand do I need to mix for each 94lb bag of cement if the mix asks for 1 part cement and 2 parts sand?

I'm getting mixed answers on the internet that a 5gal bucket full of sand is either 0.68 cubic feet or 0.98 cubic feet.

It is safer to just fill a bucket with cement and then fill two with sand to get the correct ratio?

Thanks in advance.

I have been mixing alot of cement the past few years and have found you can't rely on measures in pounds based on internet searches. I have been using a 4 cubic foot cement mixer, which really only allows about 1 cubic foot per mix. Just google "cement mixers actual cubic feet" and you will see the advertised cubic feet and the actual cubic feet they can actually mix is about half or more less. Regardless of that, they are very valuable in mixing for smaller jobs or if a bigger job is done at different times. With regards to your question, I would highly recommend if you measure out one 5 gallon bucket of cement you should actually measure out 2 5 gallon buckets of sand using a similar bucket size. I find it hard to lift 1 full 5 gallon bucket of sand or gravel so I use a marker to mark the buckets. Ie. For a 1:2:3 ratio of cement, sand, crushed stone I use two 1 gallon buckets of cement and put in a little extra, a five gallon bucket with measured sand marker line, based on previously using the same two one gallon buckets, and two 5 gallons buckets for the gravel/ crushed stone, that are marked as well, using a sharpie marker, based on those same one gallon buckets. Once you do the initial measurements and mark rhe buckets, you are good to go. Be careful when adding the water. With the mix above, using a cement mixer, I add 1 gallon of water to the mixer first, then the gravel, then the sand, and once that's mixed, the cement. Then I add less than 1/2 or maybe a 1/4 gallon of water. However, as I said I also add more cement after I 've added the second portion of water. The reason for the additional cement is because I've been adding, larger than fist sized rocks into the forms. Hope this info is helpful. The crushed stone I've been using is about an inch or slightly less wide. Of course the strength of the concrete mix depends on what you are using it for.
