Transcribed Image Text:## Laboratory Test for Liquid Limit
A laboratory test was conducted according to Method A of the ASTM D4318 to find the **liquid limit** of a soil sample. The following data were obtained:
| Sample # | 1 | 2 | 3 |
|----------|------|------|------|
| Number of drops | 30 | 23 | 18 |
| Can # | A-1 | A-2 | A-3 |
| Mass of can + moist soil, Mcws (grams) | 34.06 | 32.47 | 37.46 |
| Mass of can + dry soil, Mcs (grams) | 27.15 | 25.8 | 29 |
| Mass of the can, Mc (grams) | 11.8 | 11.61 | 11.69 |
### Questions:
1. **Briefly describe the liquid limit and plastic limit test procedure and its applications in practice.**
2. The water content in sample 1 is --.-- %
3. The water content in sample 2 is --.-- %
4. The water content in sample 3 is --.-- %
5. The liquid limit is --.-- %
This table presents data for determining the water content and liquid limit of soil samples through ASTM D4318 standards. The liquid limit is a crucial parameter in soil mechanics, affecting the consistency of soils and their classification for construction and engineering purposes.
