Determination of Fineness Modulus of Sand To determine the fineness modulus, we need standard sieves, mechanical sieve shaker (optional), dry oven and digital weight scale. Sample preparation Take a sample of fine aggregate in pan and placed it in dry oven at a temperature of 100 – 110 o C. After drying take the sample and note down its weight.

exist in a river, suspended load will rarely contain anything larger than coarse sand, and in many rivers 50100 per cent of the suspended load will be composed only of silt + claysized particles (<62 µm). The size of particles is normally referred to as their diameter although, since few particles are spherical, the term is not strictly correct.

These tips would help you balance the ratio of clay for compressed earth blocks: The basic soil containing Sand of about 6575% and Fines (Silt + Clay) of 25%. On the other hand, you can use 30% silt and 33% clay on a weight basis for the sand of 33%. There is yet another aspect of the soil grading composition limits.
