CONE 240 Midterm 1 Exam Questions AND Correct Answers
Absorption capacity - ✔✔Apparent specific gravity-Bulk
Specific gravity.
Aggregate/soil density - ✔✔1.5-1.9
Aluminum Density - ✔✔2.7
Apparent Specific Gravity - ✔✔A/(A-C), how light or
heavy the aggregate is compared to water (only took
into account water displacement/no water in pores).
Bulk Specific Gravity - ✔✔A/(B-C), takes in account the
water in the pores/voids in addition to the displaced
water.
Cc - ✔✔Coefficient of curvature = ((D30)^2)/(D10xD60)
Cc=1-3 - ✔✔Well graded aggregate
, Coefficient of linear thermal expansion. -
✔✔αL=(expansion or change in length)/(original
length*change in temperature)
Coefficient of static friction. - ✔✔Force of static friction
(tangential force)/Normal force.
Coefficient of volumetric expansion: - ✔✔Change in
Volume/(Original volume*Change in temp)
Course Graded Aggregate: - ✔✔Greater than a 4.75mm
sieve
Cu - ✔✔Coefficient of Uniformity = D60/D10
Cu=1-2 - ✔✔Uniformly graded aggregate
Cu>4 - ✔✔Well graded gravel
