Examine Some of Geotechnical Properties of Quaternary Deposits in Sharqat City/Salah El-Din Governorate and Suitability for Concrete

Abstract

The present study aims to assess quaternary deposits’ engineering properties and usability in the study area (Al-Shirqat/Salah Al-Din). Four selected stations were investigated using the modeling method and grain size analysis; deposits were classified as coarse (GS-GW) according to the Unified Soil Classification System (USCS) standard. It’s found that the specific gravity of soil ranged between (2.57-2.71), and the absorption is about (1.12-1.83) %. The gypsum content of tested soil samples ranged between (1.35-5.08) %, and the total dissolved salts ranged between (3.61-9.52) %. The results of tested samples showed that the content of organic materials (0.56-0.89) % and the pH value between (7.96-8.11) %. The Los Angeles test showed that the percentage of weight loss ranged between (14.9-19.7) %, and the stability test results ranged between (0.623-0.867), while uniaxial compressive strength values ranged between (154-189) MPa. The study resulted that the study area models are suitable for use in structural concrete works.
