For the classification of a soil to be in semi-solid state, the Relative consistency and the Liquidity Index should be
A 588 cm3 volume of moist sand weighs 1010 gm. Its dry weight is 918 gm and specific gravity of solids, G is 2.67. Assuming density of water as 1 gm/cm3, the void ratio is __________.
A certain soil has the following properties: Gs=2.71, n=40% and w=20%. The degree of saturation of soil (rounded off to the nearest percent) is _____
An undisturbed sample of soil has volume of 350 cc and weighs 490 g. After oven drying, its weight reduced to 450 g. Determine the water content (%) and & degree of saturation (s). Assume G = 2.7.
A laboratory test report gave the following results of 3 samples (three phase soil) taken from a single boring. They are as follows.
i. Water content = 20%,Ɣd= 17.5 kN/m3,Ɣs= 26 kN/m3, Silt
ii. Water content = 17%,Ɣd= 16 kN/m3,Ɣs= 24 kN/m3, Sand
iii. Water content = 34%,Ɣd= 14 kN/m3,Ɣs= 28 kN/m3, Clay
Choose the incorrect sample(s).
A moist soil sample is with an in-site void ratio of 1.57 and water content of 55%. What is the moist unit weight and the air content? Take Gs = 2.70
Match List I and List II
Consider the following statements: 1). Mica is a clay mineral 2). Rock dust particles, even of clay size are non-plastic. 3). A particles of Kaolinite is electrically charged. Which of these statements are correct?
Using the Plasticity chart, for a low compressible soil sample with a liquid limit of 32% and Plastic limit of 25% will read the plasticity Index value (in %) as
The Comparison of the surface area of the clay particles is given in following relationship. Choose the correct one.
