تأثير إضافة النورة على خواص التربة الطينية

الملخص EN

The aim of this research is to study the effect of addition of lime, which is produced by lime factory/Karbala, on properties of the soil.

Initial tests of the soil shows that it has many properties which indicate to the ability of improve its properties by using lime, such as decrease of sulfur and organic materials, but the decreasing of plasticity index and percentage of clay for soil is considered as a negative indicator to improve the properties.

After determining the maximum dry density and optimum moisture content for the soil, the treatment with lime have been done by adding four percentage weights of lime (2, 4, 6, 8) % to it.

Unconfined compressive strength for the treated soil was measured as a criterion to measure the mechanical properties (compressive strength).

The results show that the butter values of unconfined compressive strength (UCS) we get it at (6%wt) lime and treatment time (30days).
