QUESTION 3 A saturated, normally consolidated clay has a water content of 30, a liquid limit of 40, and a plastic limit of 20. The specific gravity of solids in the clay is 2.70. After demolition of an existing building, the effective vertical stress in the clay reduced to half of the prior stress. Most nearly, how much will the void ratio of this clay increase after unloading?

Two undisturbed clay samples were taken from the middle of the
overconsolidated and normally consolidated clay layers in the soil
profile shown. The water table is at the top of the
overconsolidated clay layer. Consolidation tests were carried out
on the two samples and the results are summarized in the table
below. Assume that the bulk, dry, and saturated unit weights of the
sand are 16 kN/m3, 16 kN/m3 and 19
kN/m3, respectively. The specific gravity of the clay

1. A soil sample is taken from a small test hole in a soil borrow pit. The volume of the test hole is 5 ft. The wet mass of the soil is 18 kg and the dry mass is 21 kg. The specific gravity of the soil solids is 2.65. ( m 35. 3147ft)(1 kge 2.205 lb) ( 1 lb= 0.2248 N) Determine: a. Wet and dry density (Mg/m) b. Wet and dry unit weight (pcf) C. Water content (%)...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
