• ### Measuring Soil Texture in the Lab | Fact Sheets

Particle size analysis breaks a soil into texture classes – sand, silt or clay. Soil texture influences nutrient retention, water storage and drainage. Particles greater than 2 mm are removed before analysis. The soil textural triangle is used to determine soil type based on sand, silt and clay percentages. Background. Particle size analysis (PSA) determines the relative amounts of sand

30.11.2016· There is a big difference in the size of the different particles. Coarse sand = diameter 2-0.2mm Fine sand = diameter 0.2-0.02mm Silt = diameter 0.02-0.002mm Clay = diameter less than 0.002mm. Note how the clay particles are much smaller than the sand particles – this is important as it means the total surface area of a clay soil is much greater and so the capacity to hold water is also

Hence, a correction factor for the bulking of sand has to be applied after determining the rate of bulking for the sand to be used in mortar and concrete making. As regards the rate of bulking of sand, it has been observed that it is related to two factors. (i) percentage of moisture content in the sand. (ii) gram-Size of the sand particles.
