To increase blood volume and maintain a blood pressure that will perfuse the vital organs (brain, heart, kidneys).
If plain saline is given, it takes three times the saline to replace a given amount of blood that was lost. Albumin increases the colloid osmotic pressure (encourages water to stay within the vascular system) and only twice as much (instead of three times) is required for replacement.

Albumin is a plasma expander. It's main purpose is to maintain a blood pressure. It doesn't matter how many red corpuscles a person has left if their blood pressure is zero. Ditto with saline, it's just there to maintain blood pressure. No blood pressure, no perfusion of vital organs and then you have cellular death.
Hetastarch is another plasma expander used in surgery and some trauma situations.
