Soil Classification systems provide a common language to express concisely Sjeve analysis is carried out for soil panicle sizes hydrometer analysis for particle-size distribution curse is based on Solution 8 - b It is ratio of volume of voids to total volume 9 - a It is ratio volume of voids to volume of solids 10 - d It is ratio of weight of water to dry solid which can be greater than unity or 100% 11 - a 12 - d Roof slab is not a soil component 13 - d It gives general classification based on component, grain size and plasticity 14 - a Larger soil sizes are not considered 15 - a It is indeed based on Stokes law .
