2009-4-27The mixing of sand with soil is not as effective as one might think. If the prop-er sand particle size is used and the correct amount of sand is added, some benefit can be realized. However, the amount of sand necessary to increase the overall sand content of the root zone is so great that the money and energy are better spent on by-pass.

2020-7-1However, in mortar composition used in 2 with artificial sand, this benefit was not fully achieved, since artificial grains passing through the 0.15 mm sieve had considerable quantities of grains with reduced dimensions when compared as natural grains of the same grading Fig. 3, Fig. 4. Thus, this pulverulent material added to the bottom.

2019-7-25Many fish will benefit from sand as substrate. A little known fact is that many species of fish actually consume sand. They do this to help out with digestion. For catfish and other burrowing species, sand is the prime substrate choice, as rocks and pebbles can injure these fish and prevent natural feeding behaviors.

2014-12-15Calculating the grain fineness number gives an estimate of the average sieve size of a sand sample. The distribution of the green sand has a bearing on the physical properties that can be developed by the sand system. The distribution influences the amount of bond required and the surface finish of the castings.
