“…Frost actionoccurs in areas where the soil is in direct contact with free water, causing the formation of ice lenses. The ice lens size depends on free water availability [20,21]. As water temperature approaches freezing, the water molecules form a unique hexagonal structure due to the strong hydrogen bonding that develops with decreasing temperature.…”

The Yakhtangay (Cold Valley) in District Shangla is encountering severe freeze-thaw cycles due to its elevated location and cold weather conditions. Repeated cycles of freeze-thaw action on soil cause it to lose strength, leading to settlement and a decrease in compressive strength. The objective of the study is to investigate the potential of terrazyme in enhancing the compressive strength of soil subjected to freeze and thawing cycles. Terrazyme, a bio enzyme obtained from plants and soluble in water, can reduce the water content from the soil while increasing inter-particle cohesion, leading to improved soil strength. The laboratory tests were conducted on both treated and untreated soil samples, and their properties were compared. The experimental study also included performing tests such as grain size distribution, Atterberg's limits, compaction, and compressive strength on the soil samples. Uncon􀅮ined Compression Samples (UCS) were prepared and tested for freeze and thaw cycles in treated and untreated forms. The research utilized the optimal amount of Terrazyme, reducing water moisture content from 13% to 11%. Furthermore, using Terrazyme signi􀅮icantly increased soil compressive strength, with an improvement of 40%. Based on the study's results, terrazyme is proposed as a highly effective soil admixture that can signi􀅮icantly enhance soil properties-particularly its resistance against the negative impact of freeze-thaw cycles. This study can be implicated practically to avoid freeze-thaw problems in the soil of cold regions and can be proved fruitful for the researchers to study on the particular and related topics.
