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, […]

The compressive strength of all-in-aggregate concrete is greatly affected by the silt fraction of the aggregate. At 1 and 5$ silt content (percent passing 75 um), the 28 day strength of continuously air-cured concrete cylinders was, on the average, only 28 and 79$ of the corresponding strength of silt-free concrete respectively. However, at 10% silt content, the air cured strength was 120$ of ...

Unified Soil Classification System - Wikipedia

If the soil has 5–12% by weight of fines passing a #200 sieve (5% < P #200 < 12%), both grain size distribution and plasticity have a significant effect on the engineering properties of the soil, and dual notation may be used for the group symbol. For example, GW-GM corresponds to "well-graded gravel with silt.". If the soil has more than 15% by weight retained on a #4 sieve (R #4 > 15% ...
