Geophysical, Geotechnical and Geochemistry Investigation for The Area of Kerbela`s Cement Factory

Abstract

Geophysical, Geotechnical and geochemical investigation was conducted. The samples of four boreholes were examined for classification and chemical test. In this study the surface Seismic Refraction profile showed three layers were distinguished light marl silty clayey sand with gravel, silty sand with fragment of carbonate rocks and the third layer consist of carbonate rocks. The seismic cross hole survey result showed that the fill material is non homogenous in thickness and in degree of compaction which resulted in different settlement, and the cavities and weak zones are located. . From geotechnical and geochemical study , the types of soil is CL – ML , this indicates that the soil of studies area is mainly fine grained soil to coarse grained soil with a lens of very dense white marly limestone silty gravel with sand .The MC, IC, P.L,L.L are measured too. The chemical properties of the soil of study area were investigated. The results showed that the percentages of sulphate as CaSo4.2H2O was(o.32– 2.1)% ,Organic matter was(0.0 )%,Carbonate was (39 - 94 )%, Chloride was (o,11 – 0.14 ) % respectively. PH of the soil was (7.4 – 7.9).
