Test for Silt Content in Sand - The Constructor

Sand or fine aggregate is one of the most important construction materials at any construction site. Its selection should be done very carefully as it contributes to the strength of various important mixtures like concrete, plasters and mortar. Sand should be tested for the presence of clay, silt, moisture and other deleterious materials (salts, coal, […]

carries sand that scratches rocks

The sand-silt boundary is harder to determine because silt is less than 1/16 mm, which is pretty small to see by eye. A good rule of thumb is if you can see the individual grains distinctly, even with a microscope it is sand. If the grains get too small to clearly distinguish from each other then call it silt. As for silt and shale, that is the ...
