The in-place density is determined for a soil at a proposed construction site to plan the foundation design. The in-place density test is performed using rubber-balloon equipment with the following results: Mass of soil sample obtained from test hole = 1.45 kg Volume of test hole = 0.0008 m3 (a) What is the in-place density for the soil? (b) For the foundation design, it is necessary to use the property of in-place unit weight; convert the in-place density value to unit weight in kN/m3.

Question

The in-place density is determined for a soil at a proposed construction site to plan the foundation design. The in-place density test is performed using rubber-balloon equipment with the following results:

  • Mass of soil sample obtained from test hole = 1.45 kg
  • Volume of test hole = 0.0008 m3

(a) What is the in-place density for the soil?

(b) For the foundation design, it is necessary to use the property of in-place unit weight; convert the in-place density value to unit weight in kN/m3.
