1. Introduction

1) Specific gravity of soil is average value of soil particle that have a variety of size composing minerals. And it is impoart to decide void ratio and a degree of saturation of soil. In addition finding out composition minerals or hardness , in this case, specific gravity of soil play an important role.

2) Specific gravity of soil is important feature. void ratio, degree of saturation, wet unit weight and dry unit weight. also it is important factor of ground subsidence or earth pressure.

3) Specific gravity test is ruled by the Korean Industrial Standard KSF 2308, mechanical analysis of soil.

2. Apparatus of test

1) Pycnometer :
capacity 50㎖ or 100㎖ with stoper
2) Balance :
capacity over 200gf, sensitivity 0.01gf
3) Thermometer
4) Distilled water
5) Hopper
6) Alcohol lamp
7) Sieve (NO.10)

3. Experiment’s procedure
1) Prepare the soil sample
(1) Dry the soil in dry oven for 24 hours (105±5℃)
