The Atterberg Limits (developed by Swedish chemist Albert Atterberg in 1911) quantify the critical soil moisture contents (water percentages) at which fine-grained cohesive soils transition between different behavioral states:
- Liquid Limit (LL): The moisture content at which soil transitions from a plastic state to a liquid state.
- Plastic Limit (PL): The moisture content at which soil transitions from a semi-solid to a plastic state.
- Shrinkage Limit (SL): The moisture content below which further loss of water produces no additional volume reduction.
अटरबर्ग सीमाएं (Atterberg limits) बारीक कणों वाली संसंजी मृदाओं के विभिन्न अवस्थाओं (ठोस, अर्ध-ठोस, प्लास्टिक, तरल) के बीच संक्रमण बिंदु पर मृदा नमी / जल अंश (water content) के विशिष्ट प्रतिशत मानों को दर्शाती हैं।
