Improvement of petroleum contaminated clayey soil by carbon fiber polymeric composite and diatomic soil

Volume 1, Issue 1 (Winter 2023)
Abstract
The overarching goal of this research is to use polymeric composites enriched with diatomic soil to improve petroleum-contaminated clayey soil. The effect of petroleum on the geotechnical properties of clayey soil was investigated in the laboratory in the first stage using uniaxial, direct shear, and permeability tests. The polymeric composite material was then created and mixed with the diatomic soil. The geotechnical properties of petroleum-contaminated clayey soil were studied using a polymeric composite material mixed with diatomic soil (PCD). Petroleum reduced the shear resistance, internal friction angle, and uniaxial resistance of the clay for contamination percentages ranging from 0% to 12%. Whereas 12 percent petroleum content causes the greatest changes in soil mechanical resistance. According to the results of the direct shear test, adding 5.5 percent PCD increases the shear resistance of the base material and contaminated base material to average values of 32 and 48 percent, respectively. Furthermore, the results of the petroleum permeability test show that adding 5.5 percent PCD reduces soil permeability. The results show that the improved clay by PCD can be used as a liner for the base of petroleum reservoirs.
Reading the Relationship between Historicism and the Concept of Identity in the Modern Architecture Heritage of Tehran (1310-1320)

Volume 12, Issue 3 (Fall 2022)
Abstract
Aims: The heritage of early modern architecture in the first Pahlavi era, represents the concept of identity in a new domain which could be attributed to discontinuity of traditional Iranian architecture. Historical architecture in the first Pahlavi era is one of the first attempts made to protract the identity of Iranian architecture in its new shape. The present study was an attempt to retrieve the roots and levels of the historical approach in the first Pahlavi era to explain how identity remains embedded in the modern architectural heritage of this era.

Methods: in the present qualitative study, a descriptive-analytical approach is used to decipher the relationship between the cultural values of modern architectural heritage and the concept of identity in architecture. Using relevant documents, the researcher has tried to explore the trend of architecture formation in the Pahlavi era. By studying library sources, the researcher has also tried to analyze the concept of identity in architecture as well as components affiliated with that. In the next step, an inferential approach is used to investigate the relationship between historicism and identity development in the modern architecture heritage and the results are used to analyze a series of selected buildings associated with the historicism current of the first Pahlavi era.

Findings: Imitative, schematic and conceptual historicism are three components of retrospective approach that are directly correlated with different levels of identity: formal, inferential and semantic.

Conclusion: In the architectural heritage of the first Pahlavi era, Identity is, from a historical perspective, formally transferred through a direct perception and objective adaptation to the attributes of historical architecture in Iran. In the wake of that, another group of buildings was formed, which transferred identity through content representation and as a result of indirect use of Iranian architectural elements and the refinement and abstraction of historical components. Despite emphasizing on similarities, these buildings actually depict a cultural distinction in architectural heritage of this era.
