Soil Moisture Content

CSEF · 2014 Earth & Planetary Sciences

Zachary Z. Jimenez · Reyburn Intermediate, Clovis, Fresno County

Overview

Objectives/Goals My goal was to find out whether soil, gravel, or sand took the most moisture to compact. Methods/Materials Soil Sand Gravel Rammer Cylinders/Molds Straight Edge Balances Sieves Sieve Shaker Oven Results My results showed that the soil (silt sand) required the most moisture to compact. The silt sand and data indicated a maximum dry density of 121 pounds per cubic feet and moisture content of 10%. Conclusions/Discussion I concluded after compacting each type of sample that the soil took more moisture to compact than gravel or sand. -Soil has a moisture content of 10% and a maximum dry density of 121 pounds per cubic feet. -Sand has a moisture content of 9% and a maximum dry density of 118 pounds per cubic feet. -Gravel has a moisture content of 7% and a maximum dry density of 140 pounds per cubic feet.

Summary statement

My project is about which type of soil can hold the most moisture content.
