People also ask, what is silt content?
Silt content is a fine material which is less than 150 micron. It is unstable in the presence of water. Excessive quantity of silt, not only reduces the bonding of cement and fine aggregates but also affects the strength and durability of work.
Furthermore, what should be the percentage of silt in sand and how it is tested? For example, for a given sand sample, if V1 comes out to be 9 and V2 is 130, the % silt content would be 6.9 %. The permissible value of silt content in Sand is 8%, hence the sand sample is ok and can be used for construction purposes.
Besides, what is to be done if silt content is very high?
The silt content is the percentage of sand with a diameter < 0.1 mm. If your effective size is below 0.15 mm, that means too much of the sand is very small sand particles. If the silt content is too high (above 4%), the silt will cause the water flowing out of the filter to be cloudy (turbidity).
What is silt used for?
Silty soil is usually more fertile than other types of soil, meaning it is good for growing crops. Silt promotes water retention and air circulation. Too much clay can make soil too stiff for plants to thrive.
