Alluvium sand is used in the course of various construction and repair work: masonry and screed, plaster, and in some cases, such sand acts as a filler in dyes and grouting. Some factories use alluvial sand in the production of reinforced concrete products. This type of sand is also used during road paving. Of course, its price is somewhat high, but it itself is worth the money.
alluvial sandThis type of sand goes through a special processing process immediately after its extraction. It is washed and sieved at the first stage after being removed from the soil. The advantage of this processing method is that the sand is qualitatively cleaned of clay and the smallest particles. That is, the basic advantages of such sand are dramatically increased. Alluvium sand is especially valuable in construction due to the fact that its base is completely devoid of clay deposits.
Let's compare river sand and alluvial sand to see the most striking differences. If river sand is used in the process of making a working solution that will be used to fasten the folds of bricks, then the resulting substance will have to be regularly mixed so that the sand does not settle at the bottom. Otherwise, the lower layer of the solution will be thicker than the upper one.
This factor will certainly be reflected in the quality of the finished masonry. As for the alluvial sand, it settles much more slowly, and this makes it possible to prepare a uniform consistency. In addition, this sand does not enter into an active reaction with other components of the solution due to the fact that its base is as pure as possible. Hence the conclusion that this type of sand is, perhaps, the best quality for the current day.
The most important fact is that alluvial (or washed) sand is qualitatively cleaned of clay impurities and has an increased level of filtration when compared with quarry sand.
