1. Nominal Concrete Mix Ratios. The specifications for concrete prescribed these proportions of cement, sand, aggregates, and water. These mixes of the fixed cement, sand, and aggregate ratio that ensures adequate strength are termed nominal mixes. Nominal concrete mixes offer simplicity and under normal circumstances, have a margin of strength above that specified.
Nov 12, 2014· Whats the ratio of gravel (premixed sand and stone) to cement for making a good strong concrete mix for a wall foundation? Is 4 gravel to 1 cement a good/stong concrete mix for 450mm deep x 450mm wide wall foundations? Or is it 5:1? There will also be 8mm steel mesh in the foundation too (50mm up off the base). Thanks.

Apr 15, 2010· A friend of mine said it would be best to put down a 4" base of sand mized with cement and dry lay the pavers over that. The cement will add much more to the price which is not a concern but he said that the pavers won't move and it is a better job. Any advice is appreciated. Also what is the siggested ratio of sand to cement. Thanks in advance.
Another "old rule of thumb" for mixing concrete is 1 cement: 2 sand: 3 gravel by volume. Mix the dry ingredients and slowly add water until the concrete is workable. This mixture may need to be modified depending on the aggregate used to provide a concrete of the right workability. The mix should not be too stiff or too sloppy.
