This paper examines the role of microstructure and matric suction in the collapse behavior of a compacted clay soil from Bangalore District in Karnataka State, India. The microstructure of the compacted specimens was examined by mercury intrusion porosimetry (MIP), and the ASTM Filter Paper Method was used to determine their matric suction. The microstructure and matric suction of the compacted specimens were changed by varying their compaction water content, dry density, and clay content (>2 μm fraction). Experimental results showed that relative abundance of coarse (60 to 6 μm) pores was mainly affected by increasing the dry density of the specimens from 1.49 to 1.77 g/cm3. The relative abundance of coarse and fine (0.01 to 0.002 μm) pores was affected by increasing the compaction water content from 10.6 to 26.4%. Variations in dry density, compaction water content, and clay contents notably affected the matric suction of the compacted specimens. The collapse behavior of the compacted specimens is explained from
analysis of the MIP and matric suction results.

Answer:

In refrigeration and air conditioning systems, the suction pressure' is the intake pressure generated by the system compressor while operating. The suction pressure, along with the suction temperature and the wet bulb temperature of the discharge air are used to determine the correct refrigerant charge in a system.
