Place the cone beside the pile of concrete. The pile should be about 1/2 to 3/4 the height of the cone for a concrete mixture with good workability. (SEE DIAGRAM) To strengthen samples and to promote hydration, soak concrete in water (after it is set). Wet sand may carry considerable water, so the amount of mix water should be reduced to compensate.

A concrete mixture ratio of 1 part cement, 3 parts sand, and 3 parts aggregate will produce a concrete mix of approximately 3000 psi. Mixing water with the cement, sand, and stone will form a paste that will bind the materials together until the mix hardens. The strength properties of the concrete are inversely proportional to the water/cement ratio.

Project Instructions. Step 1 Empty the mix into a mortar tub or wheelbarrow and form a depression in the middle of the mix. Step 2 Measure the recommended water amount (each 80pound bag of concrete mix will require about 3 quarts of water). Step 3 Pour approximately 2/3 of the water into the depression. If using liquid cement color, add to the mixing water.

Use as little water as possible to make a workable mix, around :1 is fine. Don't use mortar for bulk fill, it's a waste of cement. The gravel in concrete is just filler, saving cement. The concrete you mixed is sort of the standard DIY ratio, I don't know why it didn't work. While " gravel is a bit small, it can't be the reason for crumbling.
