I. INTRODUCTION

The determination ofwatercontent is an important

requirement in laboratory tests and ispart of the test included in moreelaborate tests. Water content is animportant measure in the compaction ofsoil. In order to obtain the correct watercontent, several samples at differentpoint should be taken; the samples tobe used are from experiment 1A.

II. OBJECTIVES

To determine the moisturecontent of the soil samples.

III. MATERIALS/APPARATUSES

Drying oven

Balance

Metal dish

Gloves

Knife, wire saw or spatula

Soil scraper

IV. METHODOLOGY

1. Scrape the wax from thesamples.

2. Shape the samples into either acube 3x3x3in or a cylinder with adiameter of 3in and a height of atleast 2in.

3. Determine and record the massof an empty, clean, and dry metaldish (Mc)

4. Place the moist soil samples in

different dishes. Determine andrecord the mass of the dishes(now containing the moist soil)(Mcms).

5. Place the samples into the ovenovernight to dry.

6. Determine the dry mass(MCDS) ofthe soil samples.

7. Empty and clean the dish.

V. DATA

Specimen Num. 1 2

Metal dish num. 12 15

Mc(Mass of Dish) 16g 17gMCMS(Mass of dishand moist soil)

230g 428g

MCDS(Mass of dishand dry soil)

190g 345g

Mw(Mass of water) 40g 83g

Water Content 23% 25.30%

VI. DATA ANALYSIS

Given: MC = 16 g

MCMS =230 g

MCDS =190 g

MT = MCMS - MC

= 230 g - 16 g

MT =214 g

Ms = MCDS - MC

= 190 g - 16 g

Ms=

174 g

Mw = MT Ms

= 214 g - 174 g

Mw =40 g

W= (Mw/ Ms) x 100%

= (40 g / 174 g) x 100%

W = 22.99%

SOIL SAMPLE 2

Given: MC = 17 g

MCMS =428 g

MCDS =345 g

MT = MCMS - MC

= 428 g - 17 g

MT =411 g

Ms = MCDS - MC= 345 g - 17 g

Ms =328 g

Mw = MT Ms

= 411 g - 328 g

Mw =83 g

W= (Mw/ Ms) x 100%

= (83 g / 328 g) x 100%

W=25.30%

VII. CONCLUSION

The experiment was very simple, it

did not require as much precision

and caution compared to the

extraction process, obtaining the

water content is simple, since you

only have to shape the sample,weigh it, dry it and weigh it again.
