Define the following terms
Define the terms water content, porosity and void ratio as applied to soil. Derive the relationship between the porosity and the void ratio.
In a test on a soil sample, the following result were obtained:
Total volume of soil in its natural state 645ml
Total mass of soil after oven drying 1050g
Mass of pycnometer 40g
Mass of pycnometer full of water 674g
Mass of pycnometer and dry soil 485g
Mass of pycnometer and soil plus water 946g
Determine the specific gravity of the soil particles and the void ratio of the soil.
